WTF are these street robots??

I’ve seen them in Boston, NYC, and Chicago. Anyone know?

UPDATE: From “On the Trail of the Mysterious Stikman

Bob estimates he has bequeathed 150 of these figures in various colors, shapes and sizes to the District over the past couple of years, though many have deteriorated or been destroyed.

Is Bob really stikman’s creator? I hope so. He was soft-spoken and thoughtful, unassuming in his desire for anonymity and concerned enough about safety that he places his stikman images near corners so pedestrians can look at them from the curb. The goal is not to provoke, Bob says, but simply to cause those gazing down to pause and wonder.

By that measure, I judge his work a success .
