Nice find by Cult of Mac - It's a bra with an electronic clasp that will only open once your iPhone detects that you are in true love:
"The bra works by measuring the wearer’s heart rate, and sending the reading to an iPhone app. The app then determines the true-love quotient and – if it is reached – pops the clasp, freeing the breasts within. And of course, a raised heart rate is the perfect error-free metric for determining whether to unclasp a boulder holder."
The video has to be seen to be beleved but take it in with a pinch of salt as this is a Valentine Day promotion for Japanese underwear maker Ravijour.
