Here’s an assignable RGB LED strip lamp project that can be controlled wirelessly by dragging values across a window. Another great project from Miguel Ángel de Frutos Carro:

Shows the operation of an RGB lamp using a digital LED strip. After activating the bluetooth, open the application to control the lamp. The program shows a hue palette divided into 30 rods: one for each LED from the strip. Click and drag the mouse cursor to make your own patterns. Clicking on a rod while the spacebar is pressed removes the color (switch off this led).

Part list:

• wooden support (optional),
• RGB digitally-addressable LED strip (from Adafruit or Pololu),
• microcontroller (arduino pro mini, for example),
• Bluetooth .OR. Xbee .OR. an USB wire.
