Prototypo is an open-source online typeface editor: start shaping a complete typeface using sliders, then refine spacing and outlines.
The project still has 14 days to go on Kickstarter at the time of writing this article, and it has already been funded.
In my opinion, the main problem with this project is that it looks a bit too promising and will probably end up to be disappointing (I hope I'm wrong though). The other problems, the legions of horrible typefaces that will be designed with the tool it it's that simple to use.
