Last year, for reasons not entirely clear, the owners of the Illinois Center complex of office buildings added a bright red canopy to the main entrance.
According to a blogger about Chicago Architecture, it was meant to liven up the "dark and sober" design of the black boxy office buildings.
While it does add a splash of color to the landscape, I can't help thinking that the designer is a fan of the Rolling Stones and was inspired by their logo.
