One of the first products to come from the pre-fabbed modding scene were LED fans. At the time these clear fans with multi-colored LEDs were absolutely fascinating, and the clear fans were much more interesting to look at than standard matte black fans. These fans gave us a reason to take up a Dremel and cut holes in our computer cases for windows.

ThermalTake has given us a reason to stare aimlessly through our computer case windows again with their iFlash Plus series of computer fans. These clear fans have onboard circuitry to spell out messages through its array of tiny LEDs, and is one of the most awesome case visuals I've seen in a long time.
