a brief history of the LED
For decades the blue laser was the ultimate dream in laser technology. The reason was a simple combination of physics and market economics. Blue light has the shortest wavelength of visible light. Build a blue laser diode, and you could quadruple the amount of data that could be read and stored on a compact disc, a CD-ROM, or a digital video disc (DVD) player. With red and green laser diodes already on the shelves, blue was the last of the primary colors left to tackle, and if that could be done, one could imagine a device that combined blue, red, and green and emitted white light, potentially putting the light bulb as we know it out of business. Shuji Nakamura, a Japanese scientist, achieved that dream in 1994. With the creation of the third and final color, all that was left was to put the three together.
Fast-forward 10 years later, and this technology is everywhere. Consider this fact. Edison invented the modern light bulb in 1879; over 125 years ago. It's about time we came up with something better.

Snooping around, i happened on this site that sells mood-lit objects of all types. They have bathtubs that glow green, chairs that glow purple, and my personal favorite, a wine chiller that cycles through colors.

While I was on a cruise recently I noticed that people could buy drinks with LED "ice" cubes in them. The LED's blinked Red/green in many patterns. It would be cool if they had a temperature sensor in there too and the LED could blink a special pattern or color that told the bartender that your drink was empty when the "ice " cube got warm.
