This is version V 1.25 of my Tweetshirt. It has 64 RGB-leds stiched to fabric with conductive thread and it's powered by an Arduino board.
A black shirt is worn on top of it so the leds are pretty much invisible until you turn them on.
It's a bit like a smaller scale lumalive shirt.
I made this video in the train-station before the demo just to make sure to catch in on video before it's broken again :-)
