Here you go Wild Bill...

I would love to make analog integral images. In theory it's quite simple, but there are also a number of caveats. However, someone with a sheet of film and a fly's eye array could make 3D images in that way. However, they would be pseudoscopic.

Another option is coating a plate or sheet of film with retro-reflective beads. These will act in a similar way to the fly's eye array.

Lenticular prints are another related method that might be easier in many respects.
