Look at the two tiles and ask yourself which one is the lighter tile.

then hold your finger over the gap between the two, so the gap and all the shading and highlights next to it are covered, and look at the two tiles again, and ask yourself the same question.

Are they the same?

Yeah.

What, are all your fingers busy, or sumpin?:eyebrow:

Looking at it on my phone. Big fingers, etc.

Yup, same.

The people are real.

Damn, that's cool, Pico! Thanks.

How come sometimes, I get the YouTube video right in tapatalk, and some times I see the tags and the code for the video, but it's not a link.
Huh?

Removing the Wide from the tags :

Eureka.

Now that I see what it is, I have one of those on my desk.

Google Dragon Illusion, there is a pdf you can print in blue green or red. Cut it out, fold it, tape it. Takes about 30 minutes to do.... As I recall... Mine has got to be 6 years old or so, so it's been a while. Interestingly, Kids younger than about 7-8 just can't get it. They can't seem to do the two things you have to do at once in order for the illusion to work in person. You have to cover one eye, while you move but keep your eye on the dragon... OK, three things you have to do. But the kids that get it, love it. It shuts them the Fuck up for the 5 minutes I need to get my customer's attention while I try to sell my snake oil. Love that dragon.
