RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each metal 'pixel square' contains 4 RGB LEDs and a controller chip soldered to a PCB--ws2801. Two metal flanges on the side and a 0.15"/3.5mm diameter hole in the middle  to screw them directly onto a surface. 
The total max brightness of all LEDs is about 8000mcd.

The pixels are connected by a 4-conductor cable. +12VDC, ground, data and clock. Data is shifted down from one pixel to the next so that you can easily cut the strand or attach more onto the end.

Each dot is digitally controlled, with an internal 8-bit PWM LED driver (24-bit color for 16 million different shades). The pixels must be clocked by a microcontroller.
