A small animation of a Möbius Strip, made with a Python script that generates POVRay files and then runs POVRay to render the individual frames. The normals of the Möbius strip are shown as arrows. I worked on this in June 2004.
POVRay is a ray-tracer that accepts a simple plain-text scene description language. I used POVRay a lot, both by writing scenes by hand and by generating them in some way, so there will be more posts with it.
