It's not polite to stare, but you'll be in for quite a show if you do so at these dresses by Ying Gao. He's a textile artist in Québec. Gao calls this project from 2014 (No)where (Now)here.
It consists of two dresses covered with a layer of fibers. When eye-motion sensing cameras determine that someone is looking at them, the fibers writhe like living tendrils. The effect is even more startling when the lights are turned off.
