Update 3 p.m. — For the second week in a row, the correct answer is lighthouse related. The Mirror Mirror project is inspired by the Fresnel lens of Alexandria’s Jones Point Lighthouse, according to the City of Alexandria website.

We’re back with Friday trivia!

Like last week, we’ll post a trivia question at 9:30 a.m. Comments are disabled to keep people from posting the answers. Play fair, make your best guess, and check back in at 3 p.m. when we post the answer.

For today’s trivia question, we’re taking a look at the Mirror Mirror art display at Waterfront Park at the foot of King Street. The display was created by SOFTlab, a New York-based design studio led by artist and architect Michael Szivos. The interior’s surface is tinted with full-spectrum of color with lights that respond to sound.

The artists cited a specific influence on the design of the project. Was it a kaleidoscope, a zoetrope, a Fresnel lens, or a dispersive prism?
