Kinoko Lamp

This lamp is controlled by a micro computer, so changes its color randomly time by time.

Kinoko means "mushroom" in Japanese.
Also you can see "Kinoko Magnet" a small variation of this from another page.

First idea of this thing was came from a smart color LED used to make wall displays. The LED includes small micro computer and it handles data very smart way. For example, if I send data "R-G-B" to the LED chain, first LED takes "R" and resend rest "G-B" to next LED, then the LED takes "G" and resend rest "B". So we need not many wires, but only one wire to control 1,024 LEDs in the chain.

Colors are specified 8 bit RGB like "255,0,0 (Red)". So above data "R-G-B" is actually written as "255,0,0, 0,255,0, 0,0,255".

Also price of the LED is quite reasonable ($0.33). So there is no reason to not use it.
