Negotiated study - early ideas continued

Concerning my previous idea; the problem is that I'm not sure if my scanner can come close to pulling off that kind of detail, among other aspects of the images.

Another idea stems from these scannographs I made recently with an A4 sheet of black card, and involved moving it back and forth during scanning. It made me think that I could do some kind of abstract image (more complex than this, obviously). The problem with this one is that it seems too easy.

So, to recap:
- The first idea may not be possible with the scanner I have and based on which scanner Diane Kaye uses, an suitable one would go into thousands of pounds.

-  The second idea seems too easy and not challenging enough.
