A lenticular animation device for animating coded images. A viewing device has a base structure and a pivotally coupled cover structure. A lenticular plate defines a viewing area, and a manually-operated actuation mechanism, such as a crank system, produces longitudinal, reciprocating relative movement between the platen and the lenticular plate. Lateral edge guides maintain alignment. Corresponding alignment formations retained adjacent to the platen and alignment formations in the coded image member cooperate to maintain alignment of the coded image member. Coded images can include user-completed portions, potentially in combination with non-coded images sharing a unified theme, for being colored by a user. Coded images can be exposed by removing an obscuring overlay or applying a reagent or assembled as puzzle pieces to permit user participation in the creation and animation of coded images. Opposed alignment pegs and holes can lock the cover structure against displacement relative to the base structure.
