Default Optical illusions

We need an Optical Illusion thread, here it is, just optical illusions in architecture and building I think otherwise it's to broad. A couple here to start it off.

carpet and tiles!

I wonder how often people would trip over on the illusion?

Default Re: Optical illusions

I had a weird optical illusion happen to me today that I had never tried before for some reason. Let me see if I can explain it.

Hold out your arm vertically in front of your face, palm inwards. Look at your wrist just below your palm and cross your eyes (or possibly just defocus your eyes). If you cross your eyes correctly you should see your wrist shrink in size considerably, becoming very narrow. Now move a pen or finger behind your shrunken wrist. It looks weird as the finger takes far longer to pass behind the very narrow wrist than expected.

Anyone know if this type of effect has a name?

that's a bit of a concern, someone driving might suddenly brake at that (although that's probably a good idea.)
Scratch that, I'm in favour. I recommend these for all school zones, to start with!
