The latest update to Instapaper (AppleStore link) includes six new typefaces, including two that started as MATD student projects: FF Tisa by Mitja Miklavčič (2006) and Elena by Nicole Dotin (2007). Instapaper, a 4+ rated app, allows the user to collect content for reading in a highly user-friendly environment on an iPhone, iPad, or a personal computer.  Extended commentary (and an image of Elena on the iPad) over at Typenotes.
