If you're one of those people who can't say hi without fist bumping everyone, you're gonna like what you see next.
Pedestrians in L.A. were recently introduced to a peculiar device called Walkbump, which acts like a regular crosswalk button you press for the green light to go off.
But as you can judge from the photos, you don't press it. You fist bump it. Like a true bro.
The Walkbump was designed by Los Angeles-based artist Alfredo Adán, whose intent was to bring more whimsy to a mundane activity like street crossing.
Check out the making-of process, which is no less fun than the Walkbump itself ...
Step 1: ALGINATE. Alginic acid is often used in lifecasting to create molds of living body parts.
The mold is then filled with plaster to create a master form, which is going to be replicated later.
The plaster fist is placed inside a clay box and swamped with silicone to make a mold for all the future replicas.
Lastly, the silicone mold is filled with resin. After it's done drying, the final object reveals itself!
