Plumb Bob is missing and, from all reports, Plumb Bob was last seen hanging around the Johnson Center for the Arts in downtown Troy.

Plumb Bob is one of the many objects of special interest at the Johnson Center through March 14.

Walter Black, Johnson Center exhibition coordinator, and Savanna Moore, intern, have initiate a scavenger hunt that will increase awareness of the many items that make up Ted Metz’s sculptures, Robin Metz’s photographs and Randy Gachet’s installations that are on exhibit at the Johnson Center.

“The scavenger hunt is designed for high school and middle school students but anyone would enjoy looking for items as they view the exhibits, “ Black said.

On the lists are items as familiar as deer antlers and seashells. Items that might be more difficult to locate are an anvil, a web cam and the taillight of a car.

Black said the items to find are incorporated in the artwork and visitors have to really look to find them.

“You might think snakeskin, funnels and dancing trees could be easily spotted but, when they are part of a sculpture, painting or installation, it might not be that easy,” Black said. “The scavenger hunt items may be found in the main level and downstairs galleries. The students have had a lot of fun looking for them.”

But the scavenger hunt can be enjoyed by younger students and adults as well.

Wiley White, development director, said Ted and Robin Metz are “Together Again for the First Time.”

“His sculptures created primarily from industrial objects are incredible and her brightly colored paintings are amazing,” White said. “Their artwork fills the upper level gallery. Randy Gachet’s “Subterranea” reclamation and transformation exhibit in the lower gallery is equally incredible and amazing.”

White said the exhibits will come down March 14 and encourages everyone to visit the gallery to view the exhibits and to scavenge for a variety of objects within the artwork.

The Johnson Center is open from 10 a.m. unit 5 p.m. Wednesday through Friday and until 3 p.m. on Saturday. Admission is always free.
