To me, as a commuter, one of the most impressive parts of the EZ Pass toll-paying system is the hardcore industrial "velcro" tape they give you to attach your transponder to your windshield. It's not really velcro, though -- instead of hooks and loops, both surfaces have these tiny hard plastic mushroom-shaped things that grab each other by the hundreds and don't let go. Both sides are the same, so there is only one tape (called self-mating). And unlike the loosy-fabricky velcro connection, the Dual Lock surfaces don't join until you've positioned them exactly, and then pressed them together with a satisfying "chunk." They're primarily used in industrial applications as a replacement for mechanical fasteners, but I use mine to attach my iPod to my dashboard, and tools to the wall in my workshop.
