My friend, and MAKE contributor, Alden Hart created this unique holiday display for his house, using four TinyG boards controlling a total of 16 CNC axes, to animate 16 Christmas tree balls with LED throwies inside of them. As his business partner, Riley Porter, says on Flickr: “What the hey?” Riley and Alden are the wireheads behind the TinyG axis-motion controller board. They should have boards available for sale soon.

What is TinyG – and why?
