Hello ! I've uploaded two ray-traced images of fractal Julia sets iterated with quaternions. It's: 'julia1.gif' and 'julia2.gif' They were rendered with my personal 'customized' version of POV-Ray. If you like them, let me know, I will make neater version (with soft lights, etc...) if my computer does not get exhausted before ! I'm also finishing a animated version of it (in .flc and .mpg format). I'll upload them this (local) night...
