Sure, you can buy after-market lighting kits. What fun is that?!? … especially for us Arduino-heads :-) If you aren't an Arduino-head, I could be persuaded to put together a kit.. Of course...

Compact Floating Point FPGA Hardware
Details from Compact Floating Point FPGA Hardware
I decided to build a FP with 8-bit exponent and 9-bit mantissa (and with no NANs, infinities, denorms or rounding).The sum of the bit-lengths (plus one sign bit) means that the FP number fits into a 18-bit M4K block word on the CycloneII FPGA. The 9-bit...
