[edit] Summary

A coffee mug morphing into a torus, a popular example in topology.

Rendered using POV-Ray.

[edit] Updated January 12, 2007

New colors: blue hue, brighter, softer shadows
Changed light angle
Non-linear interpolation: looks smoother and less boring
Faster frame rate
Cropped to relevant area
Overall, smaller size for a better-looking image.

[edit] Updated January 20, 2007

Removed dithering. Image now has visible color bands, but at least thumbnails won't look excessively grainy.

[edit] Updated March 1, 2007

More saturation of colors
