Obscure Three Dimensional Idea From the Early 1980s?

Now this one you'd have to be alive in the early 80's to even remember. Because I haven't heard anything about it since then.

It was the early 1980s. And I was about 11 or 12, if you must know. And there was this human interest show on at primetime called Real People.

Anyways, this enterprising inventor was trying to showcase his new invention. Basically a method for showing three dimensional images on ordinary TV. Basically he had images in front, and the background would move from side to side, creating the illusion of three dimensions. I saw it. And it worked, it seemed. He just needed to refine it a little. But thought he'd make millions off it.

He of course never did, because I never heard anything of it again.

Anyone else know what became of him? Or hisinvention? I've literally wondered all these years.
