Marcus Olsson built a sound reactive LED jar for a music hack weekend.

He named it “Don’t Look At Me LED” because when turned up to full brightness it’s really hard to look straight at it.  That’s what 576 LEDs glued around a 16cm jar will do for you.  I love the sound reactive nature of this project as well as the scrolling text feature.
