In this application there is a library including many hypnotizing wheels. You can add them on the screen, rotate them, change colors of them.

You can change rotation direction and speed. You can also change the opacity of the wheels which lead to different coloring schemes over the intersection area of the wheels. You can zoom in on different areas of the wheels and drag the wheels.
There is no aim in this application, it can be used just to relax and have fun.
