This is my basic stereogram generator. You click on the bottom colors to draw in the red box. the darker the color, the closer the stereogram will be to you. After you are done you press space and it creates the random dot stereogram
How to look at your stereogram: look at the 2 circles on the top and try to focus on both of them with each eye, which makes you a little bit cross-eyed :), then focus your sight on the random colors.
