I missed that question in the original. I made a partial keyboard for
playing TF2:

I used the LUFA library which made it very easy to get the firmware
working. The main thing I'd change is to use real pullups instead of
relying on the internal pullups. The capacitance of multiple switches
on a column cause the internal pullups to take several clocks to rise.
