Evidently I was *demonstrating* inattentional blindness. :-/

What it was meant to say was, "there are a lot of other cool demos on that page, too". I'm really fond of the live-action interruption one (with the door).

The neat thing is I got to write a bunch of this stuff into a recent proposal; perhaps I'll be using it in more depth in a few months, if we get awarded that contract...
