Daryl sez, "Thundercut's a street artist who creates these stickers that go on the "walking man" part of the walk/don't walk crosswalk lights – it makes the walking man funkier by giving him outfits, but doesn't block the light."
(Thanks, Daryl!)
Update:
Reevo shot this video of a Thundercat-remixed stop-hand in NYC.
Update 2 Kristen sez, "you should check out Scott Garner's little collection of genius animations, starring Walk/Don't Walk Man & other pedestrian signals."
Update 3: Adam sez, "Thundercut is actually a couple. Here's a feature on them from
February."
