In season 8 episode 4 (Risky Business) from House M.D., Dr. House claims he built a hand held (strobe light) device with hundreds of LED lights with which he causes a fellow doctor to vomit violently.
He mentions that the LED’s are flashing at random intervals and with random wavelengths, and this is what causes people being flashed to lose balance and vomit.
Does any one know what materials I would need to build one of these?
