Just posted over at the always-great Paper Forest, here’s a list of Paper Mechanics Resources.
I have been asked for some good resources on making your own paper automata, so I thought I’d post the books I know of that are out on the market. These are resources for strictly mechanical toys, and not pop-up books, origami books, or origami Architecture. There are plenty of pop-up instructional books out, many of which are very good, but it becomes harder to find books on automata.
Of the books listed, the only one I’ve seen before is Up-pops: Paper Engineering with Elastic Bands - I haven’t bought it yet, but having had a browse in the shops, it’s definitely worth reading. Looks like I’ll have to check out the rest too.
