I could deal with a cool logo (hey, I could even do the logo) on a black poloshirt.

Obviously the logo should also be in black, with details in black for contrast :-) Alternatively, a snow-crashy pattern of white noise would have more entropy. Someone suggested buttons; they are pretty cheap to make, and it's easy to do individualized versions using a laser printer, if you want them with your own keys or fingerprints on them....
