Walkbump, A Device Attached to a ‘Push to Cross’ Button That Operates by Fist Bumping
by Glen Tickle from Laughing Squid on (#KF1Z)
Walkbump is a device by artist Alfredo Adin that attaches to an intersection's "Push to Cross" button to make it operate by fist bumping. Adin made a cast of a fist to create the Walkbump, which he attached to the button of a Los Angeles crosswalk with epoxy.
Adin also posted a making-of video about this process.
