This rendering depicts "Balancing Ground," this summer's temporary art installation for MCC Plaza.

Last summer, it was MIMMI, a giant inflatable sculpture that hovered over the Minneapolis Convention Center plaza like a giant mood ring, allegedly changing colors along with the emotional ebb and flow of passersby. This year's Creative City Challenge winner is "Balancing Ground," a series of wooden benches interspersed with teeter-totters and surrounded by a canopy of prisms that will cast constantly changing shadows, patterns and colors.

The interactive artwork by Amanda Lovelee, Christopher Field, Kyle Waites and Sarah West was one of several finalists the public could vote for online.The foursome will get $75,000 to build and install their project in early June. They intend it to be a "space without walls, open to all."

Begun last year as a way of attracting more people to hang out on the underused plaza and interact with both the art and each other, Creative City Challenge is now a collaboration between the the city of Minneapolis, the MCC and Northernlights.mn, which puts on the annual dusk-to-dawn Northern Spark festival.

"Balancing Ground" will be unveiled at 8:30 p.m. on June 14 as part of this summer's Northern Spark event.
