The site lets you make your characters as large or small as you want, and gives you access to all of Unicode (so if you want to do the entire set of Chinese pictographs, knock yourself out). You can download your creations in TrueType or Flash bitmap format, or share them in the site's galery under a variety of Creative Commons licences. Or just browse the gallery for other users' creations, which vary from the sorts of geometric and bitmap fonts you'd expect to find to retro-styled ones, blackletter fonts, and the odd twee-looking picture font.
Which is way cool, though I can't help but think that FontShop has just wiped out its market for geometric fonts. (Not that that was unexpected; with the rise of user-generated content and better authoring tools, content is no longer a seller's market, and the standard of user-generated content is rising to the point where, even if it's on average not as good as the professional stuff, it's often good enough.)
