Use the code inside this project to make your own Op Art by warping the supplied grid and add it to the Op Art Studio. You can change the colours of the squares; use patterns to fill the squares; add outlines around the squares; etc. How this Project Works ------------------------------- We have a grid of x,y coordinates on the plane of the stage. For each vertex (X,Y) on the grid We alter X by 40 x sin(Y) and we alter Y by 40 x sin(X) This warps the grid. Then we colour the squares. This project alternately colours the grid squares black and white. It produces stripes as the number of columns is even, but if the number of columns is odd it produces a checked pattern. Op Art Starter 5 - Hemisphere is a 3D projection. It raises points of the grid in the Z direction into a hemisphere, then projects the points back onto the X-Y plane using a perspective projection.

This design is inspired by "Current", 1964 by Bridget Riley which can be seen in the Op Art Challenge project. Bridget Riley is one of the foremost exponents of Op art.
