Tetris On A Building

Around a year ago, a bunch of blinkenlights were installed in the HCI-Building of ETH Zürich. These LED spots weren’t interactive and only showed hardcoded patterns. Of course a bunch of LEDs demand interactivity, so for the first-semester party this year a giant game of Tetris was built on the side of a building.

There’s no official build log, but from what we’ve learned, the LEDs are connected to a DMX controller that is in turn plugged into a computer and the University’s ethernet. For the command and control of the Tetris game, a USB joystick was connected to an old Dell that was pulled out of the junk pile.

The software for the project, LED side of the project was written in Visual C++ reusing old Tetris routines and example code from the DMX controller. For the controller portion, everything was written in C. The controller simply dumps chars into a TCP port on the second computer. While the Tetris board was only 3 pixels wide, there was a fairly massive queue of people wanting to play.

  1. I have always wanted to do this on the side of my house for Christmas. I even went as far as buying the LED Christmas lights, and then contacting the Tetris company to see if I could get permission to license the game. That was my mistake, the basically told me that to create a replica of the game in that manor would be a violation of there trademarks.
