Textured blocks fall from the sky making up a larger, rotating cube.
Cube size can be specified. A 7x7x7 cube takes about 11 minutes to complete at 25 frames per second.
Can use up to 5 different images, images either specified on command line or grabbed from screen / tv card / image directory.
A 5x5x5 cube in various stages of completion.
I have more screensavers here.
