UPDATE 3/28/11: Looks like we finally stumped you guys. Slovak artist, Matej Krén, created this book sculpture, called Idiom, which can be found in the entrance of the Prague Municipal Library at Mariánské náměstí, near the Old Town Square. It's centrally located, near the Staromestska metro station, so you don't have to go out of your way to check this mind-boggling sculpture out. Though nobody guessed the location, T+L community member miguelcarvalho did guess the artist correctly. Check out more images of this sculpture here.
