We love it when fashion and Go Go Gadget collide. So naturally when we came across this Butterfly Flap Dress, we were tickled. The dress was designed by Alex Reeder, a grad student at NYU, who's working on changing the way we think about clothes. He's designed a white, strapless frock (ok, a little bridal, we know), with fabric butterflies attached to the front that actually flap their wings in tandem with the wearer's heartbeat, thanks to a little battery and a whole lot of brain power. Not the best thing to wear on a first date, admittedly, but still a fun thing to know exists. Alex is currently working on more informal versions of the dress, though you can't actually buy one just yet. We like to think of it as a mood ring, but prettier.
