Japanese lingerie manufacturer Ravijour has come up with a doozy. Their latest creation is a bra who's front clasp only releases when "true love" is detected. The bra has several sensors that monitor the wearer's heart rate. The data is transmitted to a phone app and through some magical hocus pocus it detects when the wearer is in the presence of "true love". Since we're all geeks I suspect the clasp could also come undone by watching Star Wars or playing the Legend of Zelda.
