Woot!!! Thanks, Al, for the great work and for the detailed write-up and congratulations on your sky-rocketing PIXEL v2 kickstarter<http://www.kickstarter.com/projects/996412530/pixel-led-art> . I'm leaving you the honor of announcing this feature on the RaspPi and BBB forums (or I will do so if you don't feel like it :D)
