cool math-y gifts?
May 12, 2011 8:04 PM   Subscribe

I'm looking for an awesome, tactile, mathy gift for a friend of mine. Suggestions?

You know, something like a Klein bottle hat or a spherical puzzle, except something that I haven't actually seen before....

I recently bought myself an awesome slide rule from ThinkGeek.

Knowing how to use it makes me feel like the geek champion of the world.

How about a Klein bottle opener? Bathsheba Sculpture has been featured on the Blue and most of her stuff is extremely math-y.

Look at the wonderful gamepuzzles at Kadon Enterprises. Super-mathy and beautiful.

I stenciled Gauss onto a t-shirt as a graduation present for a (rather nerdy) friend of mine.

What you want is this etsy store. I got a plush standard normal distribution for my birthday and it's sooo cuuuute.

I endorse the slide rule. Slide rules are awesome, us math-nerds love them.

Seconding set. It's a great game. I've even brought it traveling, and played it with people with whom I don't completely have a language in common.

If it's the fellow who can be entertained for hours by creating perfectly spherical mud balls, then maybe this isn't the answer, but it looks like Set has a version with dice now.

Maybe also see if you get any ideas from Vi Hart's website? Balloons, maybe? Or beads for dreads? I bet you could even email or call her 530 number to see if she has ideas.

definitely some good leads there, team! The buckyballs look pretty great, as does the etsy store.

aniola: Yeah, the Vi Hart-style giant pile of dollar-store snakes definitely crossed my mind...

Kaleidocycles.

Hexaflexagons, invented at Princeton in the late thirties and developed in part by Feynman, which are chains of tetrahedrons joined edge to edge and formed into rings, kind of like an extremely pointy and scary-looking polyhedral donut from Bizarro world that can be turned through the hole in ways that hardly seem possible, have been decorated with designs of M. C. Escher by I don't know who and put into a book of kits that you can assemble yourself by Doris Schattsneider.

The results are beautiful and mesmerizing, reminiscent of Rubiks Cube but with no puzzle to be solved except your own puzzled amazement.

just so you know, last time those buckyballs came up on woot, someone said the paint rubs off them really quickly and quite a few people concurred, so I would steer clear.

Gyro the Cube, a 3D-printed gyroscope thing. Check the video at the bottom of the page. I bookmarked the thing precisely to serve as a an awesome, tactile, mathy gift.

Zenmagnets.com are an alternative to buckyballs. Cheaper, and I've had mine for months (and played with them a lot) with no noticeable degradation.

Tavern puzzles?

Cool, thanks everyone for helping! I made a choice which will arrive soon...

Re Gomboc: I was actually trying to remember the name of that thing; thanks for the pointer.

So many of these were incredible. Best answers for (almost) everyone!

Now that the gift has been given: I ended up going with the Zen Magnets. I'm not a fan of the commodification of Zen, but it sounded like the highest quality version of what seemed to be the awesomest possible gift for the person involved. (Who was, indeed, the someone who enjoys making dirt balls, as aniola guessed... but that's all side chatter.) the other answers were awesome though, and will undoubtedly be revisited in the future!
