Just another blinkenlights
Really, it's all been done before. It has got past the point of being rather passé now.
Seventies gaming classic 'Pong' will reach a hitherto undreamed of scale later in April, when a version of the game is launched for play on lights adorning a skyscraper. The building in question is Philadelphia's Cira Center, a 29-storey edifice opened in 2006. The building features a programmable array of 1500 light emitting …
While you are being a little pessimistic, you are still right. Even if it hadn't been done before, is Pong really that attractive? Couldn't they of at least picked a game that wasn't based in mono color? When the game E.T. is a step in the right direction, you might want to turn around.
P.S. I actually liked E.T. :-)
Actually it's not even at Blinkenlights levels. Blinkenlights had both games and creative video. For example there was a service you could submit your video too and it would be displayed when you dialed a special number.
And they left a legacy of free (as in speech) software and protocols. In fact you can patch mplayer to output to the Blinkenlights protocol and then watch StarTrek on French libraries :)
Tower block tetris, from 13 years ago http://news.bbc.co.uk/1/hi/sci/tech/718009.stm, also mentions one from 1995.
Blinkenlights 'cheats' in a way, by installing controllable floodlights in each office. Would be more fun to hook into a building environmental controls to use the existing lights. SCADA hack, anyone? :)
Years ago (1980s?) there was a Calvin & Hobbes strip cartoon where Calvin was playing noughts and crosses (tic tac toe) on the windows of an apartment block facing his bedroom, by phoning neighbours in the middle of the night to bring their lights on.
