It's really cool and just around the corner of Checkpoint Charlie. Installations use all types of new technology. Check the modified receipt printers in the last room out, they're great
Really loved the sandbox game and the dance game. And painting in the air with my fingers really felt like touching the future. A bit expensive, but definitely worth it.
The world's first exhibition dedicated to interactive technologies and projects is located in the district of Mitte, around the corner from Checkpoint Charlie.
