The Opto-Scopic Rotator - a hybrid of a vintage slide projector [Argus Model III series] and a Penn Peer 309 fishing reel. This hybrid device will, for instance, allow you to view an image [as below, on a paper roll] in narrative form through rotation, while your subject simultaneously will be magnified and framed.
