The WS2812 Integrated Light Source from Adafruit.

NeoPixels are the common name for Adafruit's implementation of WS2812 Integrated Light Source. They refer to simple, scalable and affordable full-color Light Emitting Diodes (LEDs).

Red, green and blue LEDs are integrated alongside a driver chip into a tiny surface-mount package controlled through a single wire.

They can be used individually, chained into longer strings or assembled into still more interesting form-factors.
