Thursday Thirteen



13 Optical Illusions

Warning: Looking at optical illusions can begin to bother your eyes. Be careful!
The last optical illusion is sexy!


Focus on the blue star in the center as you
move your face toward the monitor and back again. (hereinreality.com)

Stare at the four small spots in the center of the picture for 30 seconds, then close your eyes and tilt your head back and wait... What do you see? (hereinreality.com)



Do you see a man on a burro? (about.com)

This is a famous optical illusion by Escher called Waterfall. Follow the path of the water...

Is this the face of a person or is it a word written in cursive? (hereinreality.com)

How many legs? (hereinreality.com)

Are the two purple lines parallel or are they bent?

Do you see a word? (eyetricks.com)

Mary, You've done it again. That's quite an array. I enjoyed all of them and will trace the links to enjoy some more!

Travis said...

Sometimes the longer you stare at them, the more likely you are to see the multiple images. Your clues helped me see a couple, and on a few I saw the multiple images right away.

Neat idea!

The waterfall is a triangle with a zig-zag on the way up.
I saw two burros with riders.

Now, "Do you guys actually live ON the golf course?" Of course not, they would make me take our box off every morning. We live at the edge in the backyard of whichever house we pick for the night.

How about a grammer lesson? Do you live on a street? No, you live in a yard or apartment or flat next to the street?
I'll stick with living ON the golf course, with the golf course in the back, and ON Somerton Street, with the street in front of the yard of our house.
The house has to be 20 feet set back from the golf course.

Hello again Teach! I just started a new blog, it will be bilingual (english and spanish), so here's the link to the english posts: http://jm4848.blogspot.com/search/label/%28en%29general

I come online almost every night so maybe I'll be able to join some of your memes as well, I liked the pics, but it took me longer to see the boat :)

These are great photos. I love the first one.

Adelle said...

Very kewl! Happy T13!

kay said...

I enjoyed the illusions; what fun! I have seen some of them before but I always enjoy looking. The old men and the burro riders were easiest for me to see, perhaps because of one that used to make the rounds everywhere--the one of the old woman and the young woman.

Julie said...

Now some of the optical illusions were easy...but that last one....I just can't get it!

Bwaahahahahaha!

Ivanhoe said...

Great idea! My eyes still see colored circles moving around (lol). I better get back to work then. Have a great Thursday, teach!

Denise Patrick said...

Very nice. I've seen #3 before, but this morning was not a good day for me for optical illusions. I already have a headache.

Happy TT!

LOL on 13, I saw the boat first. I loved these things before my eye went bad. Now to focus is hard.
Happy TT mine is up.

Natalie said...

My eyes are hurting...but the last one made me giggle. LOL!

I love these Mary! Thanks so much for sharing them. They are a welcome diversion in a fairly busy day!

Happy TT!

I didn't get the waterfall one?
The rest were very cool, though. I love that last one. Hubby will get a kick outta that one. :)
