/***********
*  Arduino Library for the 5 x 5 RGB LED "tile" made by Burgeon Group
*
* Natalie Freed, June 2013
*
* Uses Adafruit_WS2801 library from adafruit.com to interface with LED strips,
* adds wrapper functions for more easily playing with pixels,
* and some effect functions (drawing letters, twinkling effects...)
