Dana Johnson, an M.A. student in Public History at the University of Western Ontario, created an interactive historical exhibit, using a real story (Harry Hansell b. 1923), miltary jacket, old letters, images on a computer screen and the LilyPad Arduino and LEDs. Below are a few project photos, however you can read about the entire creation process (including code) and design journey on her blog at: http://sites.google.com/site/interactiveexhibitetextiles/home
The LilyPad & battery were sewn on the left hip of the jacket
Each of the 4 pockets have an LED that lights when it's time to reach in the pocket.
