Lego MP3 Player

Talk about modular gadgets: stuffing MP3 players inside lego cubes is about as versatile as it can get.
Alas, it's just one of those concept design renders. The nonexistent BLOC has a nonexistent 50MB of memory — why do concept designs have specifications? — and would sync and share music with one another if connected.
It's a great idea, so long as they are actually compatible with real Legos.
