PC fan can change colors

Computer has become a part of our lives. So why not to make it more attractive? Simple LED lighting in fan makes it look cool. But what if make light changing fan? CalcProgrammer1 has built a nice color changing fan with four bright LEDs mounted in corners.

The project includes the whole fan speed controller with RGB led control built around AVR microcontroller. Microcontroller monitors fan RPM, controls LED fading and communicates with PC program where in simple graphical interface you have ability to adjust fan speed, and manually select RGB intensities of each LED with sliders. This is a great base project for PC case modders.
