Optical Illusion graphic as map object???

[Gamerprinter]

I just found a strange graphic of an optical illusion on another forums site (I am inquiring as to who created it to find out more...)

Attached is a graphic of squares with varying shades of colored borders. Look at, move your eyes up and down the graphic, see the curious rippling effect?

I am sure this effect would still work in print...

I wonder if it would be worth trying out a map using this graphic as the floor for a temple, or the summoning chamber of a wizard's stronghold. I wonder if I can create a more complex design using the squares and colored lines to duplicate the effect without looking so minimal in color use... hmmmm?

Maybe if you adjusted the colors you could use it as a water fill. Then you could have nice rippling waves.

Here's another one for you - a tiling pattern based on the "rotating snakes" illusion

Here's one, I call it "holes, no holes"...

It looks to me as though it isn't the colors that matter so much in that first image as the alternating bevel and emboss that's been done, along with alternating light directions for each. You could probably get the same effect no matter which colors you chose to use. I did a quick alteration to make it greyscale. It's not as pronounced an effect--I suspect contrast plays a part in the illusion. It still works, though.

edit: And a new experiment, with a colored til pattern. Again, the change dampens the effect somewhat, but it is still perceptible.
