There isn’t much to say about Dead Frog Inc‘s “Zzzzzzzzzzzzip!” that’s not described by the title. Built for the ABS Builder Challenge, this ingenious use of the required piece as the zipper teeth looks like the real thing. With no visible studs save the ones on the angled pieces at the top, from a distance it looks like the real thing, the studs only adding to the affect by creating the illusion of crumpled fabric.
