Create and build your own font

I’ve used StumbleUpon for sometime now, its a great way of, well, stumbling upon art and design related sites you just wouldn’t usually have found.
Recently I came across Fontstruct a great little site that enables you to easily create typefaces/fonts out of grided shapes which it then creates in to usable TrueType fonts. The fonts that are created can be used in Mac or Windows applications. It also encourages people to share the fonts they have made, so its a great tool for graphic designers or design students to play with. If you choose to share the fonts these are covered by different Creative Commons licenses.
There is a video explaining the process of building a font , on first viewing it seemed as though Fontstruct had limited possibilities in terms of variety, but on closer inspection there are quite a few options and different tools, shapes to use.
It is grid based so there are certain types of fonts that just aren’t achievable, so FontShop (the creator of this site) have examples of these that can be bought, had to be a commercial side to this somewhere, which is fair enough.
Great little tool though and should increase the interest and experimentation in the sometimes over looked area of Typography.
