Circles seemed to be what caught my eye today when I shot a few quick pictures at SC Johnson today while accompanying 35 guests who are on a two-state Road Scholar / Jewish Community Center of Chicago architectural tour. These were taken in public areas where photos are allowed without special permission or arrangements.

The carport presents a myriad of shapes to play with.
Finally, there is this picture at the entrance to the Administration Building.
