Green building tetris hack

When the brainiacs at MIT get bored, they light up the place by turning the tallest building on campus into an iconic video game. Hackers overrode the tallest building in Cambridge, Mass. The successful attempt comes after a glitch-filled try to run Tetris on the same building in September of last year.

Players could control the prodigious puzzler with the ability to rotate, drop, and move blocks just like the real thing. Re:Amazing Score: 4 , Interesting. Re: Score: 1. Re:Awesome Score: 4 , Informative. Either LED systems, or they used Pentron 3-color adjustable lighting. Re:Awesome Score: 5 , Informative. Re: Score: 2. Re: Score: 2 , Troll. Yeah, just like the first moon landing.

Ho hum. More like the sixth moon landing. Pretty much, yes. The ratings for Apollo 13 sucked before the 'problem'. Re:No longer impressed by things like this Score: 4 , Funny.

No, this is Cambridge. Boston sucks for entirely different reasons. Already done before Score: 3 , Informative. I don't know how many times this has been done, but in ago electrical engineers here in Oulu, Finland made the same thing, although with regular 7-storyish building. Here's [itviikko. So by "already done before" you mean "not really"? Re:Already done before Score: 4 , Informative.

Re:Already done before Score: 5 , Informative. There were also Blinkenlights [blinkenlights. Both were made by Chaos Computer Club. Anyway, whatever the prior art was, it is always a very thrilling development. Re: And by Delft in Score: 5 , Informative.

Where I whiled away many an hour playing X-pilot, on the department's Sun workstations. And remembering when amazingly we got Unix going on a PC thanks to the hard work of a guy called Linus. Good times OK, so where's your practical example of a major hard-hack? Oh wait, you haven't done one. PIWO light show! Score: 1. Woz Score: 2. Uhm, not even old news Score: 3. As I've posted somewhere elese Score: 3 , Interesting.

Video on youtube Score: 2. They may be really good at programming things The switch can be toggled on and off, and turning it on lights up some windows on the building itself. A natural thing to do then would be to interpret our lighted-up grid as a Tetris grid. By removing all the other letters, we can turn each answer into a sequence of tetris pieces. For each lighted-up board, we can identify an answer whose sequence of Tetris pieces clears the board when the pieces are dropped at the appropriate positions.

Each board can be uniquely cleared with a sequence of Tetris pieces obtained from an answer. Matching the answers to the boards is a little tricky, but there are a few heuristics we can use to make things easier.
