A fun necktie with a classic video game twist! For details, go here: http://www.billporter.info/2013/06/21/led-tetris-tie/
Runs off a DigiSpark (ATTiny85) MCU, drives ws2811 LED pixels.
I'm working on making the code scalable and shrinking RAM use at the same time which is a challange. If you have the RAM for it, it should be able to scale up to a 256x256 display. I'g going to try and add back scoring, timeouts, and next block previews as compile time options.
Modify draw() function with your low-level LED driver code of choice. Uses assembly driver for WS2811 library right now, I'm going to change-over to Adafruit's Neopixel library shortly.
