Any octave coders round ere?

Just think, it could be the next C ;D
But seriously, I'm bored... And I already have a very rough 3d (point) rendering code. Any thoughts on how to get it doing, well, more? (ie lines, polygons, etc) ?

le bump, mainly because i haven't given up yet...

100 (random) polygon test took 12.2sec for 800x800 px (above), 6.4 sec for 600x600, and 1.6 sec for 300x300
