New to Typophile? Accounts are free, and easy to set up.
My brother sent me this link today: http://www.uniquetypes.cc/designers/index_en.html
This is a project of the Brazilian Association for the Welfare of the Handicapped Children. They are inviting designers to create fonts inspired by children suffering from physical disabilities.
Besides the chopped Arial they used on the video (which reminded me of the Fix Arial topic), I think there are a couple of good fonts when we scroll down. But I still feel kind of sad knowing the guys who conceived this project couldn't think of any other way to represent disabilities other than cutting things off.
