Oh Berlin was amazing! I didn't bother taking many photos though.
However, there are several artists I discovered during this short trip.
Alexandra Bircken is one..
See an interview with her here

Another thing: Olafur Eliasson's exhibition
at Martin Gropius Bau was especially stunning!
It's been a while since I've been to such a stimulating exhibition.

Thanks everyone for the tips.
I can't wait to go back (probably in the weekend next time for the fleamarkets..).
