Pop-out calendar - Making 3D scenes in a 'book' that folds back on itself. Each month is a triangular scene.
Pocket calendar - Function!
Danny Robert - Layers, making slightly 3D pieces. This can be achieved with sticky foam pads or acetate for a more subtle effect.
Cindy Ferguson - Simple way of creating a 3D scene.
The Toy Maker - A 3D pull-out layered scene, similar to peep-hole from Movable Books post. +Puppet theatre packaging. I love the vintage look to these pieces; it might be an aesthetic to aim for in this project.
