A good idea

Spotted this in the reception area of a college today. Seems like a good idea.

I delivered an idea generation workshop today, should have had an hour but ended up only having 45 minutes as the class got lost and were late in arriving. They were willing to stay on, so I paced for a full hour. Unfortunately the next class appeared as the room was booked immediately after us, so I had to wrap up in a hurry. Still, they seemed to enjoy it
