Shocking music game

I can’t tell exactly what’s going on here, but it looks like this electro-exerciser has been modded to make you twitch (shock) based on the music, one of the videos has it plugged in to a Ninentdo DS I think – fun stuff… – “reductronic is a old system to exercise the muscles of the human body by the use of electricity , the system was hacked to interfere the nerve system and establish sinestesia with the auditive system. The electricity current circulate trough the body at the rhythm of sound” [via] – Link.
