These are the doors to the Computer Science department. You can see my reflection in them as I took the photo, but you can also see my face. This is on a screen immediately inside the building, on the wall.
So, it seems a touchsceen computer has been newly-installed there. Someone used it to search for my blog, from there find my web site, and from there find a photo of me from 1997. Anyone going into the building from the time they did that would have been greeted by my face.
A touchscreen with Internet connectivity at the entrance to the Computer Science department where everyone can see it: what could possibly go wrong?
I don't know what did go wrong, but by lunchtime it had been turned off.
