I am going to experiment with a better mold, different materials, a full front back mold (?), opaque back layer to disperse the light better.

Also on a differenet note, there isn't a major current limit on the LED circuit is there? I have a PCB prototyper so I was going to create a printed circuit board in a ring shape with surface mount LED's around the ring for the knob area. This would require about and extra 100mA for 8 LED's. Shouldn't be a problem but I wasn't sure if it was being driven by a uP/CPU ouput pin or something silly like that.
