In addition to recently visiting MAM, I was also to the Art Institute of Chicago over the previous weekend. Here is a little videographic evidence of that visit.
Signage at the Art Institute of Chicago on Vimeo
This signage isn’t all that exciting. Based on what I saw, the loop is pretty short and it only advertises their audio tours. I really like how the mouse pointer is stuck on the screen in the upper left. At least we know it is running from a mac (the cursor is black). The display is located in an area just to the left of the main entrance of the building, in the coat check and tickets counter room.
