Yep this is a stereogram! I used [link]
to make this
it took me a while though! thanks 3dimka!
To see the image in a steriogram, move your face close to the screen, while you cross your eyes. then, slowly move your head away from the screen while slowly uncrossing your eyes. I admit, it takes a bit of practice, but eventually most people get it. Just a warning to people, but sometimes stereograms give you headaches if you look at them for too long (dont worry, 1 minute or so isnt gonna go ANYTHING... pretty sure...)
