If you want to learn more about this stuff, the guy in the video wrote a great book called Origami Design Secrets (https://www.amazon.com/dp/1568814364/). It's certainly still the book about origami design.

For something that still touches on some of this stuff but is more beginner/child friendly, I'd recommend Jun Maekawa's book Genuine Origami (https://www.amazon.com/dp/4889962514)

There's also the OSME books (http://osme.info/) which collect origami related papers.

His previous book "Origami Design Secrets: Mathematical Methods for an Ancient Art" (https://www.amazon.com/dp/1568814364) was also really, really interesting.

Unfortunately I don't. The Professor isn't putting anything online.

He did recommend some online resources for us to use though.

There's this youtube channel:

And this book:

I also have this book:

But find it to be very difficult. Not for beginners by any means.

That should help get you started.

I'm an aspiring inventor of board games, so that takes all my free time. In the past, I used to practice technical origami: The ancient art of paper folding meets mathematics. It's the best of both worlds: a very practical, yet mind-bending activity.

If you're interested, start by reading Robert J. Lang http://www.langorigami.com/ and Erik Demaine http://erikdemaine.org/.

Origami Design Secret is the best introduction on modern techniques: http://www.amazon.com/Origami-Design-Secrets-Mathematical-Me...

I also read a lot. It's not cool yet, but it will be if I get to read 100+ non-fiction books in one year. That's my goal for 2015.
