Optical Illusions

[Sis]

Here's one I posted someplace else...



My favorite illusions are drawn by M.C. Esher. My favorite of these is this one. I have it in poster size.



Find the black dots



Which one is longer?

[Sis]

Escher has been one of my favorites in the illusion department.  This is my all time favorite of his.

[Sis]

Here are some others of his.

I wish I had drawing talent like that.  Those are great.

[Sis]

Me, too!

Another one by Escher



Sidewalk art. Appears to have depth but it does't. Done in chalk.



If you watch the above images from your seat in front of the computer, Mr. Angry is on the left, and Mrs. Calm is on the right. Get up from your seat, and move back about eight feet!! They switch places!!

The one with the vase turning into butterflies reminded me of a Tiffany window I saw in Florida many years ago.

If you were on the same side of window as the light, the image looked like flowers. But, if the light was coming in through the window, all the flowers instead looked like butterflies.

[Sis]

Too bad you did't take a picture of it. That would be awsome!

Cameras were not allowed in the museum.

[Sis]

That doesn't stop some people. AHEM. If it's not a guided tour.
