There are a number of people using scanners for photography. Many different approaches, from re-housing the guts of a scanner in a more camera like body, to using a scanner as a digital back for a large format camera.
I have this recollection of one such scanner camera being used for slit scan photography resulting in very weird distortions of moving subjects. I can find many similar pages but my Google fu is failing to recall the specific one I remember…
Love this kind of thing. Tempting to get an older used scanner just to play around.
