Though it has long since been proven that the Earth is indeed round, it seems with the the way technology is progressing that people want to revert to flat, thin thinking -- or at least, the Hannes Harmes Flat Boombox does.
The sheet of stainless steel is 0.5mm thin and is fitted with skinny speaker technology. It ships as a flat package, which means customers must bend their own sound system into shape. Self assembly is a definitely scary ordeal at first, but the fun you could have with a system like this is endless. With a little bit of creativity, you could stick this sleek sound box into the most obscure corners -- behind a headboard, on the wall or underneath a keyboard, perhaps?
These futuristic babies are the definition of big sound, small package.
