Telekom house
This house is located at Leipziger Strasse and was build by the Deutsche Telekom (German Telekom), supposedly it can change colors and just about everything on the out- and inside. It is full of gadgetto gadgets – I haven’t tried it, but if you are a journalist or somehow fortunate enough you can get admission and stay over night.
If you care for some of the insights check out Heiko’s blog post about it – it’s impressive. Especially for the gadgets and technology loving folks.
