The big point is to generate the background image with gd. PHP don't have a "noise" function...
First test: basic random. (refresh the page to generate another image)
Second test: based on 3 texts (see ref at the top of the image), generate points with the ascii value of the characters. Then interpolation between points, transparent background & scrolling in js.
Third: final version of the image generation. Process:
There's a random on the height of each characters, to avoid too much recursivity.
You can get the php code by clicking on "get php source" :)
