This little working replica is about 6 inches tall with a 5 inch diameter platform to hold the circular movie sheets. It comes with a few ready-made movies and a few blank sheets to try your hand at animation/early-movie-making. A 10-sided mirrored reflector is viewed through a frame to see the animated images right-side up.
I found this on Amazon.com, but nobody there seems to have reviewed it yet. It certainly looks like fun! If you drop the $12.50 for this gizmo, let us know how you like it.
