Jos Leys

Thursday, June 29th, 2006

Jos Leys is an expert user and programmer of the fractal imaging software Ultra Fractal. If you like circles and radial symmetry as much as I do, you will love his mathematical image gallery, which is filled with all kinds of circular goodness.

Wheel Music

Wednesday, June 21st, 2006

Wheel Music is another music visualization, using similar techniques to those I used in my Whitney Music Box. Each dot in the animation represents an individual note you are hearing.

Saturday, June 3rd, 2006

Petals around the Rose is a puzzle in which you must figure out an underlying system based on the roll of 5 dice. It took me about an hour to figure it out. Some people get it right away, others take months. Here are two versions. Chris Davis’s version (flash) Lloyd Borrett’s version (javascript)
