Yesterday, I spotted quite a few small, but cute street art gems in the area between Bellealliancestr., Fettstr., Margaretenstr., Vereinsstr., Amandastr., and Weidenallee. Easy to get there with th U2 (station Christuskirche). If you go through the streets in this area with open eyes, you'll find a lot of them.
The chamaeleon is at Margaretenstr. 56, the "Elmar" at corner Amandastr. and Vereinsstr.
