This is nifty.<p>When I was in art school for graphic design, we were assigned a typography project to create a series of art pieces that used only "found typography", i.e. not fonts on your computer but, rather, type lifted from photographs of lettering in the wild.<p>As part of my designs, I incorporated Braille found in an elevator. The typography professor rejected this, leading to a 30 minute class discussion around whether or not Braille was a form of typography. In his opinion, it wasn't, and he failed me on the assignment. I still think I was right, and it's one of my favorite design pieces of my own to this day.
