Polyorama Panoptique

It was invented by Pierre Seguin as development of the earlier "protean view".

[1] The device was based on Daguerre's Diorama, of which it was a small-scale and simplified version intended for domestic use.

Most cards would be designed to include small cut-out parts through which the light would pass.

Other parts of the cards may be made of thinner material to create a glowing effect.

The device also included separate doors at the back which allowed the user to control the degree and direction of light.
