Amazing, I just finished writing a program to do the same thing, with a smaller subset of polyhedra, specifically for printing or CNC work. If I had found this a month ago I might have saved myself hours.

  Can I see anything you have printed/CNC'd?

    What I just finished is the layout software, I'm hoping to start some CNC work soon. https://github.com/alanbernstein/dymaxion https://github.com/alanbernstein/dymaxion After starting the project, I found this: http://www.spiralsbysteve.com/globes.php http://www.spiralsbysteve.com/globes.php. If we can produce something that looks half as good as this, I'll be thrilled. See also: https://www.youtube.com/watch?v=UbQsOneX-8c https://www.youtube.com/watch?v=UbQsOneX-8c

It's strangely missing the most common one (UTM zones).

This is absolutely gorgeous. Doesn't work on my mobile device but well worth investigating on desktop. Fun for me since I used to have a hobby of making various polyhedra with unit origami [1]. Apparently it's an update from this older site. [2] [1] https://www.amazon.com/Unit-Origami-Multidimensional-Tomoko-Fuse/dp/0870408526 https://www.amazon.com/Unit-Origami-Multidimensional-Tomoko-...

  I recommend this MIT OCW for people interested in the math behind origami and folding problems: https://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-849-geometric-folding-algorithms-linkages-origami-polyhedra-fall-2012/index.htm https://ocw.mit.edu/courses/electrical-engineering-and-compu...

I love the poetry of lines spiraling out of Africa. A metaphor for the dispersion of our species.

Very interesting. It would have been really cool if you could drag&drop the "globe" around in realtime (i.e. shift things so Australia was at the center, or Canada, or wherever.

  You can! Hold shift and click-drag!

    Cool. It's freaky and weird watching as you drag the world around :)

Can you print this?
