The lamp has the style, it's up to you to add some during construction. Nevertheless, instructables user "silverbyte" has documented his excellent RGB lamp that has the option to control colour, hue and cycle speed. The hardware and sketch is quite simple, however the lamp housing itself is most professional and wouldn't look out of place in a living room. The following video is a time-lapse of the construction and demonstration of the lamp. Skip to 4:30 to see the lamp in operation:

If you're looking to make more creative designs with LEDs, consider the Freetronics RGBLED: full colour module. It includes a bright RGB LED on the top of the board and a WS2801 constant-current, addressable, multi-channel LED driver on the back. This smart module can be daisy-chained, so you can connect a number of these together in a string and drive each of the module colours individually from your microcontroller.
