OSTBLOCK: http://www.myfonts.com/fonts/volcano/ostblock/

Ostblock is an OpenType font with 5 stylistic sets that let you easily build 3-dimensional letter-buildings. It is inspired by the apartment living blocks in the center of East Berlin built in the 60s. The regular font contains more complex letter buildings, while the simple font has simplified and plain letters in two different levels.

Thanks in advance!!
