Man, I'm not sure if I even remembered the name correctly, but years and years ago, Doug Henning had put out a "Thing" (for want of a better word) that you folded and when it was finished, you could continually flex this folded contraption into several diferent mutations, and each time a different color would show...I believe there were as many as six or more different colors.

I am sorry to be so vague, but it has been a long time!!!!!

But, does ANYBODY have the faintest memory of what I'm talking about, and could perhaps direct me to instructions on how to fold it?

No, I'm not crazy.

There is a commercially available set of these with Escher prints on them they're pretty cool. Here's a couple links you should find interesting...

I don't know anything about Doug Henning's deal, but they're really not some secret magic thing.

Thanks for the link!

Doug had one available that had "magical sayings" written on the spaces.
