There are many images in which letters/text appear when you stare hard into them, called Autostereograms. I want to know how they are created. This is an example (here's the hidden image):
I want to create an album cover, so what steps are taken to create such an image myself?

I've known these previously as Single Image Random Dot Stereograms (SIRDS) or 3D Stereograms and if you are simply looking to create them rather than know the process (which Wikipedia will helpfully teach you about) then I've found a couple of options.

1Uuu I saw a shark! Too bad I'm one of those people who see these images only when I cross my eyes, and I see the images "carved" not "bumped". Good question. +1 – None – 2012-04-10T20:07:38.663
Let me see if I understand your point, you are asking about steganography?
– Diogo – 2012-04-10T20:20:15.980Steganography is the more general concept of embedding hidden images within something else. But yeah. @DiogoRocha – slhck – 2012-04-10T20:22:25.027
no not exactly steganography. the aim is to stare hard to see beyond the visible. – Kartik Godawat – 2012-04-10T20:22:52.220
So, take a try on this site. It is a online steganography generator.
– Diogo – 2012-04-10T20:24:24.8973@DiogoRocha No, that's not what he wants. The "secret" message should be a 3D stereogram visible to the human eye, not a digital watermark. Just like the image in the question — it's a shark if you look closely. – slhck – 2012-04-10T20:30:51.413
lol, I looked from all the different angles and saw nothing beyond color points........ I thought Kartik was looking for a way to hide a image inside another... now I understand the point... – Diogo – 2012-04-10T20:33:44.260

@TomWijsman Why did you not post that as a answer? – Scott Chamberlain – 2012-04-11T13:38:53.363

@ScottChamberlain: Why should I be copying Google results into answers? Links only are discouraged. I found these in under a minute, now I wonder "what problem the OP has with using these"...
