Full-screen VITS now there's an oxymoron!

Full-screen pulse & bar used to be seen occasionally.

A very early memory for me from the days when our set only received the single BBC TV channel, was seeing a black cruciform pattern on a white background, which I would learn much later were called "Art Bars". Art for artificial, as it was electronically generated.

If I can trust my memory from 60 years ago, I seem to recall there was always a tone on the accompanying sound when this patten was showing.
