An electric kinetic sculpture created by retired U.S.

An electric kinetic sculpture created by retired U.S. Air Force Master Sgt. Daniel Holmes is shown at his home in Lowell, Mass., Jun. 1, 2018. Holmes uses his sculptures to teach Airmen various electronic and mechanical skills in order for them to maintain equipment used at the Sagamore Hill Solar Observatory of the 2nd Weather Squadron, Det. 2, in Hamilton, Mass. The face that adorns the sculpture represents Masconomet, chief of the Agawam tribe, who is buried next to the observatory. The Agawam played an important role in the early development of Massachusetts towns in the mid-1600s. (U.S. Air Force photo by J.M. Eddins Jr.)
