Well, rayt (that's its short name) is quite basic and limited, there are
only two different object types: planes (with no borders) and spheres. I
only ever tried grayscale images and it's just plain raytracing with
reflection and transparency.

I consider it quite finished, because pure raytracing with its shadow
rays it's just too bad at distributing light, and can always learn to
use povray. I might try to implement refraction some day though.

No, but I could zip it up and mail it to you if you want.
