For Halloween 2011, I designed a wearable camera costume using my Nikon DSLR.
It's a fully functional, complete with an LCD display, built in flash, shutter release button/wireless remote control. It is also capable of triggering my Alienbees strobe lights with a Paul C. Buff Cyber Commander, and winning any costume contest with the push of a button.
See how it's made and see it in action here:
