Thats briljant!

but the link to the image doesnt work any more.

How does is work? I've been studing moire behavior for sometime now, and this would love to use this effect for an art (school) project

Shouldn't this be called Steganography.

I think it is a kind of Steganography.

But it looks random pattern, so it will wondered that messages are concealed.

Steganography is a form of Cryptology.

@CrackedCipher No. Steganography conceals the *existence* of the secret (i.e. try to hide something in plain view). Encryption conceals the secret, but does not conceal the existence of the secret (i.e. an eavesdropper can see the scrambled message and knows it's there, but cannot determine the secret it contains without having the key).

I liked the effect a lot. Could you explain how you made it?
