The crosswalk button helps you safely cross the street, so why not show it some love with a fistbump? Art director Alfredo Adan Roses decided that the act of just pushing a button wasn't enough, so he created the "Walkbump."

The artist made a silicon mold of his hand and then glued resin fist duplicates onto crosswalk buttons around Los Angeles. Above each yellow fist, a sticker tells pedestrians to "fist bump to cross." The people of L.A. were quick to catch on and soon everyone was connecting fists with the poles. There's no word yet how many people went out to buy a snapback after the interaction.
