Squeak is really shining here though, because I can just hook things up to sliders and play around until I get a feel for it. I'm also playing with my words a bit: I don't understand in any concrete way why noise approximates natural phenomena. AFAICT no one does. It kind of reminds me of that Fermat conjecture, "here's this thing we don't understand and couldn't prove for a really long time that always worked no matter how many times we tried to break it." I think it's the mysterious part of noise that drew me to it.</div>

Could be very niche graphics-nerdery, but who knows, the Croquet crowd might find ways to have fun with it at least. If I hear from people who'd like to play with it, I can clean up the code, add an example, and put it up under the MIT license somewhere convenient. Why not, right?</div>

</div></blockquote><div><br></div><div>I definitely don't want to do the "yet another implementation of X" thing. It's pure Smalltalk code, no OpenGL stuff, which has ups and downs, but is at least different from what David Faught mentioned. Once I'm confident that I've got the bugs out, I might actually rewrite it in slang and make a VM primitive.</div>
