Stereograms. Ahhh, the magical world where hidden 3D images appear and where you appear as a nutjob describing the 3d image for those who don't know how to see.

Where?
There!
Where?
There!
I don't see it.
It's there! There's the head, the tail, and the wings!

Look, it's floating in the air right in front of you!
Okayyyy. I'm gonna go now.
Wait! Don't go! It's really there!
...
I promise!
