[Markus] noticed a lack of 7 segment LED displays that could show RGB. Like any hacker, he sought to remedy this. The solution he came up with was to basically remove all the electronics from the plastic body of the display. He then mounted new surface mount RGB LEDs in the correct places. This may be a bit messy, and definitely increased the footprint in this layout, but as you can see from the pictures on his site, the final result is quite nice. What uses can you think of for these?
