Olympus (the camera company) is smart. The created a Photography Playground in Berlin full of art installments designed to give you cool things to take pictures of, presumably with the Olympus camera they lent you when you arrived. I brought my own (I'm a Canon man), so I just went to town :-P
There were lots of toys like mirrors
And masks
Crazy costumes
Fun backdrops
And lots of shiny things
Rooms with crazy lights
And complicated strings
Optical illusions
Oh and lasers
LOTS of lasers
And if you looked closely, you could find words of inspiration on walls and windows
But in the end, it's all about your photographic eye.
