Solar powered clothing is nothing new, but solar powered clothing that makes you get off your rear and work out? That is new. The Motivational Moody Workout T-Shirt created by Lingon at Instructables was built with the intention to motivate the wearer to do more than stand around.
The t-shirt is created with a LilyPad arduino -- the same technology we saw in the bike turn signal jacket a couple years ago -- and a solar panel.
Using blue LEDs sewn into happy face patterns on the LilyPad board, and a ball tilt sensor, the shirt determines if you're moving around in the day time and smiling (or frowing) at you depending on your activity level.

It's a motivator to get out in the sunshine (since it only works when it's soaking up solar energy) and get moving!
