Picture of Open Heart Hoodie
This hoodie has an open heart kit on the chest that is removable using magnetic snaps. The kit is driven by a lilypad arduino and battery pack attached to the inside of the hoodie.  It runs various patterns through the LEDs when the zipper connects the exposed conductive threads.

I was inspired by these instructables:
Open Heart LilyPad Brooch
TV-B-Gone Hoodie

The open heart kit was created by Jimmie Rodgers.
