Part 2: I go down to the smaller scales with a model of a Fox. The fox model is from Origami Omnibus by Kunihiko Kasahara, which has the full instructions.
Part 3: I go back to make a larger model using thicker paper to simulate the effects that will happen with the smaller scales.
Part 4: I scale down the crane model to small scales.
Part 5: I go to smaller scales with a dinosaur model (a loch ness monster type dinosaur).
Part 6: I make an even smaller crane model and conclude the series.
Apparently claiming magic is not acceptable to the Instructables community.
I believe the following video will help to answer your questions.
I look forward to any comments! This is my first video post, so let me know wat you think about the editing, pacing, etc...
If you make some tiny origami of your own please post them!
Edit: I made some changes to the video to improve the quality, but after those edits I really felt that this should be broken up a bit better as a step by step Instructable, which is posted now. Thanks for the feedback everyone!
