To most people, a bench is a place rest, to relax, to wait.

But to interactive artist George Zisiadis, a bench can be much more than simply an object where we take a load off or pass the time. It can be a place to play.

When you sit down on Zisiadis' San Francisco bench, it's instantly converted into a makeshift merry-go-round propelled by your feet.

Zisiadis designed it for the city's Market Street Prototyping Festival, which for three days transformed the street into a public platform where people could experience and explore a variety of prototype designs.

The goal of the "Bench Go Round" is to connect strangers in a moment of play.

"Connecting with other people is one of the great joys of being alive," Zisiadis told Fast Company. "The Bench Go Round playfully reimagines a new way for city infrastructure to help us interact and have fun with each other."

During the festival, people lined up for a spin on the bench, and as you'll see in the video above, they couldn't help but smile.

Zisiadis hopes to build a permanent version of the bench that will continue to thrill and engage people — and help make play a part of their daily lives.

"Play seems to be this thing that only children are allowed to do in designated, fenced-in areas," he writes on the Bold Italic. "As daily life gets only busier and more stressful, we need to reengage with our inner children now more than ever."

Zisiadis has created numerous other pieces of interactive art, such as Pulse of the City, an installation that turns pedestrians' heartbeats into music.

He's also crafted one-of-a-kind events such as the New Year's Eve Experience, which involved converting a 20-foot long truck into a "penthouse apartment" where participants were greeted with champagne and party hats to celebrate a New Year's countdown. Over the course of one November evening, a "new year" was celebrated more than a dozen times by more than 500 people.
