From the Flaming Pear website:
"Knot lets you create large 3-D color animations and stills of beautiful abstract knots. You design the knot's form, colors, motion, backgrounds and lighting - or design and render entire animations automatically. It's an endless source of gorgeous moving backgrounds and photocollage elements for your work."

Serial: 646053593 seems to unlock versions 2 and 3, untested with 3.71. 2 and 3 work fine on Sheepshaver under 7.6, I think 3.71 requires OS8 or 9 so I have not yet tested it.

Version 3.8 has some updated features.
