Meet Copper, a puzzle that could take a lifetime to finish. Jenna Frye, the Hopkins Extreme Materials Institute/MICA Artist/Designer-in-Residence for 2018–19, modeled this 3D-printed so-called impossible puzzle after the grain structure of copper. The 274 interlocking pieces—roughly 1,000 times bigger than actual copper grains—are made of bioplastic filament. "Even with a map, showing what number piece goes where, it's tricky to put together as you have to build it from the inside out," Frye says. People can try at Frye's exhibit titled Symmetry and Fracture, which runs through Jan. 10 at the Milton S. Eisenhower Library's Q-Level.
