Back in 1991, there was a raytracing package released for the Amiga called POVray. I always wanted to have a play with it, but it wasn't until I found myself recommending it on a topic at SCU a day or two ago that I actually bothered to try it. Having knocked up a Newton's Cradle model, I decided to go for something a bit closer to home and raytrace some Morph Balls.
These morph balls were created using POVray's ultra simple, ultra powerful Scene Description Language. For those who are interested, the scene description file is as follows (yeah, it's tiny !)
