Sorry about title, but I my descriptive skills are failing right now. Worth checking out maybe.

Thought I'd bang this link up in case it's on any use. It's from the fault analysis group at University College dublin. Not a set of complete paper models, they are a geology "starter" kit. But they do offer some interesting shapes and it's covenient having someone else work out the paper plan form.
Take a look at the "normal fault and relay ramp" option as an example. I've just thought of a number of uses for this one.
There are another set of cubes on the site. Which I am sure there is a use of, but still trying to figure one out.

Then go to educational material, then paper models near the bottom of the page. Won't let me grab a link. If anyone can think of a use, let me know.
