|Steroscopic Image of Random Aircraft Carrier|
You may have seen images like this claiming to be 3D, and I know you always think how can this be 3D? I know this because I've been there.
But never fear, as I have cracked it!
You can see the 3D image by crossing your eyes. Crossing your eyes? Well not exactly crossing them, your left eye looks at the right image and your right eye looks at the left. Confusing? Yeah I was too but, you can get a basic explanation here.
Now you can watch any 3D video on youtube without glasses, gloat over all your friends who can't.
