Image Description, by

This is a small program I wrote which implements a nice effect reminiscent of the art of Vasarely. This picture shows four shots from the program. It's a square grid which twists and bulges with time. The top left shows a bulge with a texture mapped grid. The top right shows the same but with just the grid and it's inverted in the bulge. The bottom left shows the grid twisting, I like the lines view because you can see what's going on, the bottom right is this same effect with a texture added. Lots of screensavers are built on this code and it's a nice effect to add to your demos. I'm will have a small tutorial soon. Source code is available at
