Here's an extension I built around adafruit's HL1606strip (non-PWM) library. It let's you control a 2D grid of HL1606-based strips. Suggestions & pull requests welcome!

Re: Open Source Addressable LED Matrix
Very cool! This would be great if you could scroll text across it and maybe connect to a computer running processing or something to display an RSS feed. It seems the colors on the library for the basic 1606 control are out of whack? Blue = green?
