Staff at Kink.com try out the popular new present that many got for Christmas: a wooden box that sits on the head of a bondagette, which has electronics that closely monitor the wearer's heart rate, blood pressure, and GSR (galvanic skin response). When the wearer has an orgasm, the little lid at the front of the box pops up (see woman standing second from left for an example). It's kind of like the pop-up timer on a turkey.
