Balls!

Hi all,
I haven't posted anything of my own for a while.
Here's my latest effort: a vt100 obfu (sorry as ever to windows users...).
The bumpmap could do with rounding and the raytracing (!) routine isn't ideal, but i'm reasonably happy with it
- maybe i'll fix these problems for an updated version at some point.
Update: I've done a new version with a generated sphere and a better shading routine. it's here.

The * at 0,0 is the lightsource.

ps. i got the shape from http://music.hyperreal.org/artists/b12/gallery/ascii/fl/sphere.htm
The result of searching (given my job i'm not going to say googling!) for ascii art.
Update: added link to updated code

I like the ball title, but the code kind of reminded me of Mickey!
Runs really cool too! Thanks!

I like how the specular reflections mirror the shiny surface of my xterm. Good job!

Works for me on win98 under cygwin. It's great! Thanks!

That's pretty cool though IMHO it's more of a concrete poem than an obfu. We need attributes for posts :-P

All I can say is: WOW!
