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/ http://www.langorigami.com/ and Erik Demaine http://erikdemaine.org/ http://erikdemaine.org/. Origami Design Secret is the best introduction on modern techniques: http://www.amazon.com/Origami-Design-Secrets-Mathematical-Methods/dp/1568814364/ref=cm_cr_pr_product_top?ie=UTF8 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.
