For those new to Stereograms, check out "Cosmos" it is an easy one to see.

I can always see the 3-D effects, but I never can tell what they are...

I've wondered if it is possible to see them in inverted forms, say one way concave, and the other convex? Is it possible to bring this 3-D effect into being by finding a near focal point, and also a far focal point?

I remember "seeing" a moving one on TV in the 80s ....very cool ...still have it on VHS....shame I can never see the darn things!

Frost Spiral is the best stereogram I have ever seen as far as the number of levels it has (I count at least 9 levels) It is also one of the easiest ones to view.

Thanks Dave for letting us know that there are moving stereograms out there. I never would have even thought to look for such a thing.

I found quite a number of video's but this one is very easy to watch and graphics are gorgeous. Very 60's
