I didn't detect the effect. I used two pieces of aluminum foil wot I made
little holes in and painted black around, but I didn't mess around with it
enough. I have no doubt that the effect exists/works. All I was saying was
that when we look at a picture normally we know, inherantly, the respective
distance and relation of familiar objects in a familiar setting. A picture
of a field with mountains in the distance and a fence in the foreground
tells us immediately that IF we could percieve it in 3D the fence is
nearest then the field etc.

I think it might be interesting to see if the 3DVG effect is possible in
say a simple still life with a small ball up close and a large one further
away, but because of positioning appears to be the same size as the small
ball. Would it appear in 3D? I doubt it. When you remove the visual depth
clues surely there is no way for the effect to work....

It still is very interesting though. The brain is an amazing organ.
