Anotations

Scope note:

Optical toys that create moving images, consisting of a series of sequential drawings mounted on the inner wall of a revolving drum and facing the center where they are reflected by a many-sided drum containing a set of mirrors equal in number to the number of drawings and revolving in the opposite direction, the whole to be viewed through a special eyepiece; developed in the late 1870s as an improvement over zoetropes and phenakistoscopes.
