When implementing some of these image representation ideas, sometimes they turn out exactly as I expected, sometimes better, and some are complete duds. The above pic was an example where I got something that I expected would look cool, but I didn't expect it that it would look like... coiled viscera, or brains or something. It's not entirely successful in that it's pretty hard to make out what it is representing (it's the Mona Lisa). Needs some tweaking to convey contrast better. Also, the intestine-y look invites a nice, gooey, glistening rendering style. So it's time to break out the Renderman.
Renderman, of course, is the 3d rendering technology created by Pixar. I can't affort the 12 grand or whatever for their flagship renderer, but thankfully there is a superb knockoff called 3Delight that's quite nice indeed, and the first license is free. There are also a couple quite passable open source Renderman-compliant renderers out there, notably Aqsis, which I have used quite a bit.
Renderman is a 3d renderer, but there's nothing to prevent it from being used to make 2d images. And the Method Artist just loves the procedural shader model. So watch this space for some 2.5D procedural madness.
