I agree with Raul. This is nice!
I also agree about mentioning that the supporting code (crypt, int2rgb,
etc.) is in the JoJ link somewhere in the youtube description (About
page?). Others not on the mailing list will not have the luxury of knowing
about JoJ. In fact, I also hurriedly went to the video without reading your
full email and had to return to see if there was somewhere to find more
about supporting code.
Thanks for making this nice video.
Vijay.
