Adafruit will not be shipping orders Monday May 30, 2016 for the federal holiday, Memorial Day. Orders placed after 11 AM EST Friday May 27 will go out Tuesday May 31.

Total project time, starting from zero Python experience to having a working demo, photographs and a tutorial, was about two days. Great things are afoot!
Update: Here's a quick test Ladyada did in Adafruit warehouse last night, shot with a phone!
