20mm Clear Digital RGB LED Pixels (Strand of 20) [LPD6803] ID: 307 - $45.00 : Adafruit Industries, Unique & fun DIY electronics and kits: "RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each RGB LED and controller chip is molded into a 'dot' of silicone. The dots are waterproof and rugged. There are four flanges molded in so that you can 'push' them into a 20mm drill hole in any material up to 2mm/0.08" thick. They're typically used to make outdoor signs. Compared to our '12mm' dots, these are clear-coated and brighter.
