Hi all

An experiment I have been working on has just hit the point where I feel comfortable showing it off: A rotate-able 3d-ish chunk of terrain, created using Perlin noise and the threshold capabilities of the BitmapData object.

[Viddy it here](http://www.eccesignum.org/flash/scorched/071104/).

Warning: In its present incarnation it is something of a processor hog.

Code to follow, after cleanup and performance optimization. I look forward to critiques and comments.
