Has anyone ever tried Gelato? Not the lemoni flavored kind, ;-)
Gelato, the free rendering engine from Nvidia. It appears that it's
not for the faint of heart...it has plugins for 3DMax and Maya,
there's a script to export from Blender...It utilizes GPU computation,
running off the memory of Nvidia graphic cards, so it's supposed be fast.

Parthenon, another free GPU renderer which is sort of obscure is
also lightning fast, but the documentation is in Japanese and it's script driven.
If someone wrote a UI for it, then you'd really have something!
