Held every year in Bremen, Germany, Poetry on the Road is an international literature festival. The theme for the festival in 2007 and 2008 was designed by Boris Müller, a professor at the Interface Design programme of the University of Applied Sciences Potsdam, using software that generates a graphic design based on words. There’s an interactive demonstrator that lets you enter your own words to generate designs – quite interesting. Check out the viewer for 2008 here and for 2007 here.
