I did these raytraces in college, using POV-Ray on a 100Mhz Pentium. Click on any image to see a larger version.

As I recall, this room is the first large scene I ever did. The things on the table are a checkerboard and a vase. The beaver cartoon in the frame was done by a friend of mine.

The brick wall looks a little funny, but otherwise I think this bowling alley scene is OK.

The strange spheres on the floor are supposed to be glass marbles, but I never got them to look right. I think the razor blades look pretty good though. I always wanted to get rid of the marbles and render a pile of razor blades alone, but never did.

This could look better with a different floor and background.

I think I found this parametric transcendental surface near the back of the CRC Handbook of Mathematical Curves and Surfaces; it might have been called a "Devil's Curve" or something like that. POV-Ray 3.5 (released in June 2002) introduced support for direct rendering of parametric surfaces, but this was not supported when I did this rendering. Instead, I built a surface mesh, from a simple uniform triangular mesh in parameter space. Of course, there are better ways to generate the mesh. At one point, I computed the surface normal at each vertex, and rendered a nice smooth shape, but I can't find that rendering anymore; maybe I never rendered it at 640x480 because it took too long? Unfortunately, I can't find the POV-Ray source, or the C code I used to generate the POV-Ray source, anymore.
