Have you tested the edited Script?

What about the "random fill"-script as starting point?

Another point: When people speak of »random« they often seem to mean a limited randomness, so one should give some thought to how one intends to limit the randomness within any variant beforehand.

Its just a matter of writing some functions on how you want to manipulate the layer - normally by using scriptListener, then creating a loop to loop though how many times you want to repeat something and adding a random calculation into the rotation, size, etc. For example in this image, I wanted to create tiles in a somewhat close order to the original image, but I wanted each tile offset a bit. So I create some code that made a selection, but I added a random element to it to move it around, then I moved it back into order, so the tiles were lined up.

Basically to add some randomness to a number you use something like this:

var myRandomNum = Math.random()*theRange + theOffset

You times the Math.random by how much of a spread you want, the you either add or subtract the offset.
