I just listened to a piece called: 'Human Directionals' Twirling for Your Attention on NPR.

Here is a link to a video called Street Moves about one such "active advertiser".
Here is a link to information about "human directionals" from a company called 1-800-great-ad.

Was reinterpreted by Yahoo in the early 2000's

rodeo clowns (to draw away attention)
and giant rats (to knaw through reason)
