He used three images and repeated each many times.
Much like we use to do with Audioscope bars.
Each of his Red, Blue, and Silver bars had a link from a Arcive page of an old webtv-zone lmage link.

I downloaded them and saved them. I would hate to see this get lost.
especially if he is no longer around.

In my Saved Version I closed one of the open spaces between the bars.
And I added a string of flashing lights in the space where the wider gap was.

Why they were there I can only guess that originally there were images there.
That didn't get saved when the Zone went out of business.
