This was my main draw to the Neopixel; Adafruit has written a custom Arduino library and provided sample code to get things up and running quickly. Adafruit says that the Neopixel line of products ...

Realizing this, [Josh] wrote a simple demo program to drive over 1000 NeoPixels – an 11 meter long strip – using 1K of RAM on an Arduino ... a display where every NeoPixel is an element ...

The build relies on an Arduino Pro Mini to run the show ... The individual triangles are each lit by a NeoPixel LED, which are both addressable and capable of lighting up in RGB colors.
