dime-story vasarely (processing sketch)
// Inspired by Victor Vasarely*, I created a mechanistic color grid with inset squares or rectangles.
// The color palette was primarily built using a Complementary set of reds and greens,
// with a hand-picked blue and yellow for added vibrancy.
// The algorithm prohibits the horizontal repetition of a background color,
// and will not alow an inset-shape to be the same color as the background.
// * particularly by http://4.bp.blogspot.com/-JvA1kOVrVoQ/TbtLGxQ7fxI/AAAAAAAAAZU/n8wyXMlmDus/s1600/colour_vasarely5.jpg
