The Giant Tetris Build. Everything from Hardware to the Web. We're building an LED array that will hang on the window of TrepHub, run by a raspberry Pi. People walking by outside can just hook up to the Pi's wifi (via smartphone browser) and control the display (I.e play Tetris or space invader). Gamers I the community can develop other low res games for the display too (we're building he game framework out in python and using Flask for the web controller interface).
