Bear with me, because I don't know what these are called: In the various MP3 players, they have visualizers, some of which look like 'space warps' or some such. I understand these are generated on the fly, and cant be controlled. I'm making a mini movie and the cloud-like effects I see in these visualizers would be perfect for exterior shots. Only problem is, I can't find software that can generate these effects. What I need: Software that allows the design and control of generated 'scapes' (I'm a bit lost here) where I can specify the color, speed, particle effects, frame size and frame-rate (720x480 24fps, 30fps, 60iFps) A number of videogames have visuals like what I'm trying to describe, and with a joystick, one can move around this environment. I'm on Mac OS X, but I do have access to a Win98 PC.

New versions of Wondertouch's particleIllusion should be released for Mac OS X in a few weeks. I've heard that the current Mac versions have some problems with hardware acceleration.

It's available for Windows, also.

The application is hardware-accelerated, so it can create these effects practically in real-time, on a halfway decent system.

Issue #64 of Digit Magazine included the Windows version of particleIllusion SE 2.0 on its cover CD. The magazine even has an upgrade deal that lets you buy v3.0 at a significant discount.

They're called fractals, and you can generate them with loads of things, bryce being an obvious choice. The ones ni winamp have, lets say expressions, to link their motion to the audio being played. Because they're fractal though, you can't controll it in as much as, that swirl to the left, kinda thing. But you can alter density, detail levels, speed, colour, etc. Hope it helps.
