Praxinoscope kit and assembly method
Abstract:
A kit of parts and method for forming a praxinoscope with a base, an outer wall to be secured to the base in a cylindrical configuration, and a mirrored inner wall to be secured to the base in a faceted, substantially cylindrical configuration concentric with the outer wall. Image strips with sequential images disposed thereon can be disposed within the outer wall, and an axle member concentrically disposed through the base and the upper panel permits a rotation of the praxinoscope to produce animation. The inner and outer walls can be secured to the base by teeth that project from their lower longitudinal edges in combination with inner and outer rings of apertures disposed in ring shapes in the base. An upper panel can be similarly retained atop the inner wall. Notches at the proximal ends of the teeth can positively engage the apertures in the base.
