I had been thinking about John Lynes' suggestion for using a laser pointer to "copy" rays from a horizontal dial (or any other type, for that matter) through a sill-mounted mirror to a ceiling dial. I'm attaching a (small!) sketch of the sort of 3D pantograph support it would take. I'd appreciate any suggestions from the machinists/mechanists out there, on making it workable!
