Human Mirror

Some people from my old theater department are in charge of Improv Everywhere. They do cool and fun stunts - their latest is a Human Mirror on the subway, where they found 16 pairs of identical twins to ride all together in a subway car. Check it out here.

Their complete mission list is here - all worth watching. My favorite is Anton Chekhov.

Here's the video of the Human Mirror, but be sure to check their website too.
