RGBling Bling Bow Tie

It changes color!
Three RGB LEDs are embedded into this bow tie and controlled with an ATtiny85. I had an extra 5VDC step up battery holder (http://goo.gl/dRbyi) that I used to power it.
The LEDs are glued into the holes of the bow tie print. I was trying to solder it as quickly as possible, so I'm sure it would be possible to give it a cleaner look in the back and insulate the exposed wires.
