Actually, I've not seen that one before (but do STR something similar). No idea how it works, though.

I find that if I stare at it, it turns greyscale. I wish I knew how the mind filled in the blanks of what you see.

Actually, I should probably find out, since it seems like a useful thing to know.

It's interesting that I see most of the movement when I've just refocused my eyes. If I stare at the same bit of it, the movement mostly stops after a few seconds, but as soon as I move my eyes and look at a different bit, the whole thing starts spinning again.

Not entirely sure what this proves, though :-)

But still, it moves!

Have you seen this one?

Scary. It seems to stop rotating if I squint really hard. It's somehow scarier that you get the same effect even if you print it out in black and white.

Is it available as a tiled background for Windows desktop?
