Not all hacks need to be made up of servo motors, wireless radios, and PIR sensors. Sometimes hacking has a softer side, of which [Katie] reminds us with her latest creation.

Her LED quilt incorporates 64 hand-sewn LEDs, all of which were painstakingly attached with conductive thread. The same thread was used in a sewing machine to build the conductive grid that powers the LEDs. One half of the circuit was sewn into the front of the quilt in the form of 8 rows, while the columns are sewn into the back side. All of the rows and columns meet in the corner of the quilt, where they are attached to a Lilypad Arduino using simple metal snaps.

The LED matrix panel was then tested, then sewn into an actual quilt. The finished product looks completely innocuous until lit up, as you can see in the video below. We think it would make a great nightlight replacement for a child, especially if programmed to display soothing light patterns.
