By now I see those things all around!! But find ick jut :]
TramFace is baffled:
You can see this one at a box in the front right of a Berliner Niederflurstraßenbahn.
SpoonFace smiles at you:
Found at a drum break (yea!) at a practice last weekend. Must be some kind of rust.
SnowSkull looks directly into your soul:
Isn’t that a pretty clear 3/4 of a skull? Found at Oberbaumbrücke when I came back from Jimpster at the Watergate club. And right beside it: (really just recognised it) you can spot a horse with wings!! Or isn’t it a Unicorn? Ok, the horn is just greased backwards.
