A while ago I created Compyx, a multicolor font (using Abdobe/Mozilla's SVG-in-OpenType technique). It'll show up like your average singlecolor font in browser that don't support this yet, but it'll show up in classic green/gray colors in Firefox, and soon Chrome.
You can download the TTF/WOFF in the blog post.
I was wondering if you know a good place to upload this font so it can be used by more people. It's pretty much open source/public domain.
