About a year ago, a friend and I fiddled with making 2D sprites with Cartoon Editor. It's freeware -- can't beat that price -- has vector drawing capabilities, imports bitmaps, and can export Quicktime movies of your creations spinning nicely around their center points. We fed the movies (which were of fish cartoons downloaded from the web -- we are admittedly goofy people) through w00tware's m2s, made masks in GraphicConverter, and tossed 'em into EnRLE. I don't remember all details about Cartoon Editor, but I did figure out how to do an engine (er, fish) glow.
Cartoon Editor (for OS X) is here, if anyone is interested: (url="http://"http://www.personal.utulsa.edu/~jeremy-wood/software/editor.html")http://www.personal....are/editor.html(/url)
I know fancier packages can do this (ImageReady, I'd bet), but Cartoon Editor gets to the point fairly quickly and is more, well, free. It's not perfect.
You could use this method to animate more serious art, but at the time of our experiments, I remember wishing that I knew a good amateur cartoonist. It would be a hoot to have a cartoon-themed TC. Could be anything from original B & W doodles (think how small the plug-in file could be) to Futurama! Heck, do Spongebob, if you can figure out the viewing angles! Dilbert! Doonesbury! Rex Morgan, M.D.!
Anyway. I blather.
