Firefly guitar pick lights up in tempo

The Firefly is an LED guitar pick with a sensor system that helps it flash in sync with your music, putting a light show quite literally at your fingertips. The battery-powered gadget can be recharged via Micro-USB. The addition of the lighting technology, sensors, and algorithms means this isn't going to be a four-for-a-dollar pick. The pledge price is $49. This does give you several options. The Firefly Original responds to playing motions. The Firefly Duo flashes one color on the way up and another on the way down. The Firefly Insanity adds an element of randomness by choosing its own color for down-strokes.
