Little cardboard robots with flags stating their destinations, released as a street art project in New York City. The artist made them disposable, expecting that most of them would die in the wild; but over the months, random strangers came through time and again, rescuing the bots and guiding them to their destinations. She states, "Never once was a Tweenbot lost or damaged."

Another discovery by the folks at boingboing.

Airports aren't fun places these days, which makes for excellent random brightening. Twenty "Agents" of Improv Everywhere spent a few hours at JFK Airport greeting strangers with flowers and personalized Welcome Home signs. Their event writeup explains in detail how it was done, how people reacted, and showcases some fine wide-eyed expressions.
