Overview of the Op Art Movement

Op Art (short for Optical Art) is an art movement that emerged in the 1960s. It is a distinct style of art that creates the illusion of movement. Through the use of precision and mathematics, stark contrast, and abstract shapes, these sharp  pieces of artwork have a three-dimensional quality that is not seen in other styles of art. Op Art Emerges in the 1960s Flashback to 1964. In the United States, we were still reeling from the assassination of President John F. Kennedy, encapsulated in the Civil Rights movement, and being invaded by British pop/rock music. Many people were also over the notion of achieving the idyllic lifestyles that were so prevalent in the 1950s. It was a perfect time for a new artistic movement to burst on the scene.   In October of 1964, in an article describing this new style of art, Time Magazine coined the phrase Optical Art (or Op Art, as its more commonly known). The term referenced the fact that Op Art is comprised of illusion and often appears to the human eye to be moving or breathing due to its precise, mathematically-based composition. After (and because of) a major 1965 exhibition of Op Art entitled The Responsive Eye, the public became enraptured with the movement. As a result, one began to see Op Art everywhere: in print and television advertising, as LP album art, and as a fashion motif in clothing and interior design. Although the term was coined and the exhibition held in the mid-1960s, most people who have studied these things agree that Victor Vasarely pioneered the movement with his 1938 painting Zebra. M. C. Eschers style has sometimes caused him to be listed as an Op artist as well, though they dont quite fit the definition. Many of his best-known works were created in the 1930s and include amazing perspectives and use of tessellations (shapes in close arrangements). These two certainly helped point the way for others. It can also be argued that none of Op Art would have been possible—let alone embraced by the public—without the prior Abstract and Expressionist movements. These led the way by de-emphasizing (or, in many cases, eliminating) representational subject matter. Op Art Remains Popular As an official movement, Op Art has been given a lifespan of around three years. This doesnt mean, however, that every artist ceased employing Op Art as their style by 1969. Bridget Riley is one noteworthy artist who has moved from achromatic to chromatic pieces but has steadfastly created Op Art from its beginning to the present day. Additionally, anyone who has gone through a post-secondary fine arts program probably has a tale or two of Op-ish projects created during color theory studies. Its also worth mentioning that, in the digital age, Op Art is sometimes viewed with bemusement. Perhaps you, too, have heard the (rather snide, some would say) comment, A child with the proper graphic design software could produce this stuff. Quite true, a gifted child with a computer and the proper software at her disposal could certainly create Op Art in the 21st century. This certainly wasnt the case in the early 1960s, and the 1938 date of Vasarelys Zebra speaks for itself in this regard. Op Art represents a great deal of math, planning and technical skill, as none of it came freshly-inked out of a computer peripheral. Original, hand-created Op Art deserves respect, at the very least. What Are the Characteristics of Op Art? Op Art exists to fool the eye. Op compositions create a sort of visual tension in the viewers mind that gives works the illusion of movement. For example, concentrate on Bridget Rileys Dominance Portfolio, Blue (1977) for even a few seconds and it begins to dance and wave in front of your eyes. Realistically, you know  that any Op Art piece is flat, static, and two-dimensional. Your eye, however, begins sending your brain the message that what its seeing has begun to oscillate, flicker, throb and any other verb one can employ to mean, Yikes! This painting is moving! Op Art is not meant to  represent reality.  Due to its geometrically-based nature, Op Art is, almost without exception, non-representational. Artists do not attempt to depict anything we know in real life. Instead, it is more like abstract art in which composition, movement, and shape dominate. Op Art is not created by chance. The elements employed in a piece of Op Art are carefully chosen to achieve maximum effect. In order for the illusion to work, each color,  line,  and shape must contribute to the overall composition. It takes a great deal of forethought to successfully create artwork in the Op Art style. Op Art relies on two specific techniques. The critical techniques used in Op Art are perspective and careful juxtaposition of color. The color may be chromatic (identifiable hues) or achromatic (black, white, or gray). Even when color is used, they tend to be very bold and can be either complementary or high-contrast.   Op Art typically does not include the blending of colors. The lines and shapes of this style are very well defined. Artists do not use shading when transitioning from one color to the next and quite often two high-contrast colors are placed next to each other. This harsh shift is a key part of what disturbs and tricks your eye into seeing movement where there is none. Op Art embraces negative space. In Op Art—as in perhaps no other artistic school—positive and negative spaces in a composition are of equal importance. The illusion could not be created without both, so Op artists tend to focus just as much on the negative space as they do the positive.

David Walker Analysis of the Appeal Essay - 1564 Words

David Walker’s Appeal to the Coloured Citizens of the World, but in particular, and very expressly to those of the United States of America, â€Å"promoted racial solidarity and moral elevation with fervor,† and is as much a political source as it is religious. His Appeal adamantly argues against oppression and slavery while encouraging a vivacious and lively spirit amongst the black community, in the hopes of promoting unity and diminishing the acceptance of mistreatment from their white counterparts. To convey this message, which was presented in a mannerism that was extremely radical, Walker uses the bible and what can most clearly be defined as a Methodist theology to support his stance on the issues of society. David Walker was â€Å"born a†¦show more content†¦In writing the Appeal, Walker was looking to initiate a drastic move amongst the black population of The United States of America. Those who believe in the Methodist doctrine believe that all people are created by God, in His image, and regardless of sex, race, or color, all people have the same inherent rights and Walker, who was adamant about change, incorporated this belief throughout his writing. His appeal to the American public however was not only to abolish slavery, but once slaves were free, to allow them all the Biblical rights they are due, as the Egyptians had to do when the Israelis were freed from slavery under Pharaoh. As an abolitionist urging black people, free and enslaved, to rise up against their oppressors by any means necessary, especially by violence, Walker’s purpose in writing the Appeal was to persuade his audience that enough was enough and that the time had come to take a political, social , and economical change. According to Hinks, Methodists were usually more willing to place â€Å"the powerful God of Christianity†¦ on the side of social and political justice.† One religious message that Walker conveys through this Appeal that supports this claim, wasShow MoreRelatedRoots of Resistance Essay1605 Words   |  7 PagesFilm Analysis: Roots of Resistance a Story of the Underground Railroad In the movie Roots of Resistance a Story of the Underground Railroad, the filmmaker makes some very strong points.

Blood Disorders Free Essays

Blood disorders describe problems associated with blood components such as red blood cells, platelets, enzymes, plasma and white blood cells. The characteristics of blood disorders depend on the real blood disease. Blood disorders can also be associated with hereditary characteristics whereby some disease causing organisms are transferred from parents to children. We will write a custom essay sample on Blood Disorders or any similar topic only for you Order Now Blood disorders or diseases lead to continuous bleeding in case of an injury and poor blood clotting. Blood diseases result from abnormalities in blood itself or defects in blood vessels. The three given cases in this paper relates to various blood disorders associated with lifestyle, genetics and injuries. The first case of four years Amy, who complains of tiredness al the time and eats pasta, breads and hot dogs, and drinks artificial fruit punch, is a case of anemia. Amy is a pale and picky eater and her mother is single and cannot afford to feed large family so it means that her daughter consumes unbalanced diet. Anemia is a blood disorder whereby the number of red blood cells is insufficient to supply enough iron to body parts (Hadorn Ernst, 1961). Iron deficiency is the main cause of anemia and children are vulnerable to this disorder. Main characteristics of anemia include fatigue, slow healing of wounds, weakness, drowsiness and dizziness. Amy complains of being tired all the time and this is one of the main symptoms of anemia. The blood disorder is diagnosed through examination of blood sample and in many cases; the red blood cells are small and pale. Anemia is treated by iron tablets and consumption of vegetables such as spinach and foods rich in iron. Anemia in this case of Amy can be prevented through consumption of well balanced diet and avoiding any circumstances that can lead to excess bleeding such as injuries. In the case of Marcus, a five-year-old African American male whose mother wants the nurse to screen his son for trait is a case of hemochromatosis. It is a case of hereditary blood disorder that has been transferred from mother to son. Hemochromatosis is one of the common hereditary blood disorders that make body tissues to absorb too much iron. Being a hereditary disorder, hemochromatosis is known to develop from dietary iron intake (King E. John, 2002). The blood disorder leads to severe iron overlap in children and young adults. It is caused by defect in HFE gene responsible for controlling amount of iron observed from food. Children who inherit the defective gene from one parent become carries of the disease but may not develop it. Symptoms of hemochromatosis include joint pain, abdominal pain, and fatigue and heart problems. The blood disorder is diagnosed by collecting information concerning family history, physical examination and routine blood tests. Hemochromatosis is treated by controlling the amount of iron getting into the body through phlebotomy process. Prevention of hemochromatosis is very technical as it is a hereditary disease transferred from parents to children through genetics. However, it can be prevented by protecting the body from excess iron. In the case of Richard, he is likely to have thrombosis as is analyzed in his body condition of numerous bruises and tiny red marks around his eyes. Thrombosis is clotting of blood vessels because of blood clot that blocks a vein or artery. Blood clot is caused by damage of blood vessel or changes in blood flow. Symptoms of thrombosis include numerous bruises, swelling of body parts and red spots as a result of blood clot (Wood M. Stephen, 1997). Physical examination of body parts is the best alternative for thrombosis diagnosis. The blood disorder is treated by an anticoagulant that allows thinning of blood. Thrombosis can be prevented through wearing of pressure stockings and use of blood thinners. References Hadorn Ernst, 1961, Developmental Genetics and Lethal Factors, Methuen, Ursula Mittwoch.

Scholarship Application free essay sample

Have you have ever had a dream that you went for, and accomplished? Although I’m still a high schooler, I have big dreams for my future. Becoming a teacher is very important to me. Some adults don’t realize that the best years of most teenagers lives are their high school years, or also that the most crucial learning years of your life are in grade school, because your brain is still young and developing quickly. So true is this, that its crucial to learn as much as you can while in school,{{CS}} you’ll have better learning skills as an adult. That’s why I want to teach kids as much as I can and make the biggest difference in their lives as I’m able. I would like to receive this scholarship because I need any financial help I’m able to receive. This year I have really buckled down with my school work. We will write a custom essay sample on Scholarship Application or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Faced with senioritis, it finally knocked some sense into me, and I realized that I’m not going to go anywhere in life with poor grades in school. My future plans consist of going to Cowley County Community College to get my core classes out of the way: later to transfer to a university (preferably Emporia State) to get a teaching degree. I would like to become an elementary school teacher, or a high school history teacher. Whether I become a history teacher or an elementary school teacher does not matter to me, because I will try to major in both (but only one at a time). A certain sport I particularly like is volleyball. If I become a teacher, then I plan to be a volleyball coach for high school girls also, and being a teacher makes it easier to become a coach at the school that I want to teach at. Volleyball has by far been my most favorite memories of high school. I don’t want to coach it just because I love it, but also because I want to make young girls love it also. If you try your hardest and are close together as a team, then you’ll have what it takes to win. One thing that I’ve learned while playing volleyball with my team is to never take anything for granted; especially not high school. Moreover, I want to go far enough in life to be able to aid students and athletes that need it.
