Once every semester our student representatives organizes a special themed party which is electrical engineering like illuminated with tons of LED “Throwies”. These so called “Throwies” are made of of a coin cell battery, some tape, a magnet and a LED. Combined with a logo sticker are they placed on the walls of the club like this:

After a while all of them are used as a stylish accessory and everyone is blinking and glowing. So I got the idea to go a little more extreme on this one. My plan is to stick as many LEDs as possibly on a jacket and control them individually to get a huge display.
