Script to Create Image on the Fore Edge of a Book

Hello,

Here is an example of what I want to do:

http://blog.eyemagazine.com/?p=149

If you bend the pages of book, you can see an image (which is a word) on the fore edge of a book.

I was wondering if there is a script or if I could create a script that would be able to make this in indesign?

I have never made a script before, but I was imagining that it could go something like this:

Duplicate an image

Paste in place on the next page

Select the content inside the frame

Move the image x distance

And repeat all above for the next page.

then there would be an option for how many pages this would be done.

Does this sound at all possible, or am I just making this completely up?

Thanks in advance.
