Grand Central Improv

As with the Obama music video, everyone has probably already seen this, but I wanted to post it just in case. This is the (probably) latest stunt by Improv Everywhere, a group that gets hundreds of people together to cause "scenes" in public. You can look at their events as anything from a practical joke to an interactive work of performance art. I believe they're most famous for the blue shirt prank at Best Buy a few years ago.

This video in particular is actually a wonderful example of people interacting creatively with their spaces. One of the things that makes these scenes so brilliant is that they executed and then abandoned without explanation. I'd have to think that witnessing one of these scenes would be pretty shocking... in a good way.
