“This month’s I Spy isn’t far from last month’s,” writes Megan Szakasits. “You really seem to be going for engineers’ hearts with back-to-back ‘I Spy’ challenges!” says Eileen Hoekstra. “Back to the G.G. Brown Building,” writes Sara Kitzsteiner. “The photo is the top cube of the new sculpture” there. “I love that the picture this month is of a sculpture outside the building last month’s pictured sculpture sits in!” quips Judi Taylor. “I hope all of last month’s entrants get this one right!”

“The sculpture … [is] called 3 Cubes in a Seven Axis Relationship,” writes Susan Daron. “It’s a kinetic cube design by Philip Stewart,” writes David Karl, picking up on last month’s clue. According to Karl, Stewart hoped his sculpture would inspire students to “think outside of the box.”

The piece honors the late Chuck Vest, a Michigan engineering dean and provost who went on to become president of MIT. According to a U-M press release, Vest “had an interest in establishing a collection of artwork on” North Campus. The sculpture will be dedicated in 2018 as part of mechanical engineering’s 150th anniversary celebration.

Twenty people correctly identified 3 Cubes. Our winner, drawn at random, is Chris Pannier. He will enjoy his $25 gift certificate at Ayse’s restaurant.
