Optical Illusion Puzzle
A different kind of puzzle today!
What's the optical illusion demonstrated by this image? I'm not looking for a technical name, just a description of what you can see in this image that isn't true. Oh — I don't mean the moiré effect in the small thumbnail. [Edit]Added another version of the illusion, where I've removed the anti-aliasing. The results in moiré effects, but you may (try) to ignore these. Answers in Spoiler:
as usual please!

No, that's not it. I've added another picture with the centre removed (because I've also turned off anti-aliasing with the new picture, and the centre detail is too fine to work without anti-aliasing).
If there is any apparent warming of the colours towards the centre, it's an artefact of the conversion from an eps to pixels. The illusion isn't a small effect that you have to strain to see. I might be without internet access over the weekend — I'll post the answer to this puzzle on Monday. Last edited by pdurrant; 07-15-2010 at 06:56 AM. |
