Today at the end of the BAG meeting Sally Blakemore will demonstrate two more paper engineering projects. This is part of an ongoing series for those working on the “Santa Fe Origins” collaborative book, and anyone interested in paper engineering.
First are the animated tabs and pulls. This mechanic operates with multiple slots through the front that contain items that lift when the tab is pulled down. Use it for any kind of reveal-and-conceal idea; for example, bugs under leaves or birds flying up or dancers or a village where the houses and the trees pop up.
You can add as many windows and struts as you wish.

The second mechanic is the two-track wheel with two windows. This can be used for showing comparative things. In her example, Sally has humorously shown things you can accidentally run over with your car in New Mexico: snakes, tarantulas, scorpions, stink bugs, rabbits, chipmunks, ravens, beetles, and more. (Don’t worry, folks—it’s not real.)
