Here are a few semi-lame-o ray traces that I did. The first and third were just for fun; the second was for my final presentation in the Aircraft Design class I took last year. Point being, even a moron like me can produce these things.
And here a few much more impressive ray-traced images that should make you say "Wow. That's just so awesome."
If you think ray-tracing is gonna increase your chance of getting a date Friday night, you're probably wrong. Nonetheless, you still may want to download the latest version of POV-Ray.
