I love seeing this. I worked in the university computing department in college and this sort of thing wasn't an uncommon sight under the desks. People also had all manner of exotic keyboards.
The most elite setup, as I recall, was the Kinesis Advantage combined with pedals. The keys on the Kinesis are recessed in these sort of cups that your fingers rest above. The idea is that this reduces the distance that your fingers travel moving between rows. I could never get the hang of typing on one of them, but people swore by them. Adding the pedals for shift/ctrl/esc was supposed to further reduce the need to stretch your fingers and get them into awkward positions. People also swore it made them faster and of course it looked and sounded super cool.
