Anyone messed around with this
? It's a quick and dirty web-based font creation tool. It's limited to 'bricks' and such however so don't expect to make smooth-as-silk detailed vector fonts. It's good for prototyping pixel font stuff fast though (and then use them for your window system). I haven't been able to make a fixed width font however.
This could be a fun time-killer for some here. Most of the fonts on the site are boring novelty fonts, though
