Okay, I was browsing about the place, and suddenly this tab pops up.

I've no idea what I clicked on to get to it, it might've been on UG, I don't know, but I had a look, and thought WOW!


In case you find it confusing, here's what you do:

Look at the bottom two images
Kinda go cross eyed so they "merge" into one
Focus slowly on the merged image (between the two normal ones)

It'll appear all 3D and awesome!

Sorry if this was on UG and I just clicked it without noticing
