Here's a brief comment.

I just saw something in a seminar that I've never seen before.

The medium for the present talk is an overhead projector. The speaker was presenting a brief example but didn't have a good picture to show people. He was struggling with describing what the system is, so the next speaker (sitting in the front row) handed him a slide of that to borrow and show. (The next speaker is going into more detail on that topic.)

You gotta' love mathematical relief pitching...
