This cartoony abode in Germany was designed by American pop artist Rizzi. Dr. Seuss would be envious.
Rizzi, an American pop-artist who died in December 2011, was most famous for his 3D artwork and this is probably his largest piece. American readers of a certain age may remember him best for his artwork for the cover of the Tom Tom Club‘s first album (they were an offshoot of Talking Heads). (source)
