Well, it does have a sense of non-antialiased or of too sharp edges. Maybe they're some kind of artifact, I don't know, but it doesn't look good in all the awesomeness of the picture itself. Maybe some blur could correct it. > > One of these days I'd like to delve into tachyon more and improve our > interface, there are definitely things that could be improved.

Blender has two main approaches to raytracing: The first is by using its own internal renderer, which has quite many features usable from inside Blender. The second one is by using Yafray (Yet Another Free Raytracer), which must be installed externally. Also, there are other, less common approaches, which usually involve exporting to a file and using that in an external program, like POV or some commercial renderer like Brazil. > > -M.
