Someone on deviantART, duh. :P (to be more specific, a manipper turned 3D render artist who specialized in Kaa/snake pics)
Anyway, I'd ask that if anyone does have his collections, please don't dump them all at once. Nobody likes to have to dig through a bunch of the same artist's pics.
I think I have some of Rhachadi's old manips somewhere. I'll post a few later, if I find them.
