A web of silvery tracings emanates from an angular design recently circumscribed in a very well-trod public building -- if the ensemble is taken as one, likely far and away the most visited building in Chicago on any given day -- as part of an ongoing, award-winning update to some dreary, if efficient, Modern spaces. (So well trod, in fact, that I'm surprised that the original terrazzo could receive this inlay without requiring extensive refinishing, although I suppose the material's quite durable.)

Interestingly, and probably unintentionally, the hexagonal shape of this design complements the overall building complex -- a rare one in Chicago which often rejects rectilinearity and the grid in favor of flowing 60/120-degree turns and a NW-SE axis, although in retrospect that last bit seems a poor choice that will be rectified. This particular space has its own name; better yet, describe where the arrows might lead someone. Yes, that's a bit of a trick question.

The feet may be a hint, especially with the new image. Also note the grain of the original terrazzo; you may be among the hundreds of millions who have spent hours, or at least many long minutes, elsewhere in this building (or its similar neighbors) staring at it out of exasperated boredom.
