How Many Boulders Are There?

How Many Rocks Do You See?

Now this is an interesting find! Aihira Kenji, the one responsible for Rope Illusion and Football Player Stereogram, created this fine little animated gif file. The game is simple – All you have to do is count how many boulders are present inside the picture.  Is it 9? No, wait! There are 10! No, wait…I give up. Can you at least spot when or where does the extra boulder appear/disappear? If you stare at the animation for a while, solution becomes obvious.

Remember those nervous Leprechauns? They pulled the exact same trick back in the old days! If your memory serves you well, you’ll remember we had Mandarin warriors and Mad Scientist’s Soccer Team that did the same.

No matter how much experience I have, and how long I have stared at those previous animations, I never had luck with them. Just like my troubles with seeing stereographic images. Perhaps some people are born to see them, and some not. Enjoy our newest addition!
