Where's the Off Switch on this Dress?

Skip ahead to the nine or ten minute mark on this video of a runway show last week in Paris. The clothes alter themselves; lifting their own hemlines, making slits, spitting out beads, and zipping up bodices. A hat loses it's brim. It looks like a digital special effect but it ain't.
If you're still not interested, it ends with a nude supermodel.
