Around The World in 30 Sonobe Units: An Origami Globe of the Earth
Around The World in 30 Sonobe Units: An Origami Globe of the Earth
We interrupt the normal mission of TonysPlate.com, which is to help you calculate nutrition
information (http://www.tonysplate.com/what-we-do.php), to bring you this bit of paper-folding
fun.
The following pages contain specially patterned paper and instructions for creating a model of
the Earth assembled from thirty Sonobe units. A Sonobe unit is a piece of modular origami that
can be combined with other Sonobe units to form geometric solids. Join three units together,
and you can make “Toshie’s Jewel,” a triangular solid. Join six units, and you get a cube.
Twelve units make up the stellated octahedron. And thirty units make up the stately stellated
icosahedron.
What we here at Deep Spring Solutions have done is to project the data from a NASA map of
the earth (http://visibleearth.nasa.gov/view_rec.php?id=2433) onto the faces of the Sonobe
solids using POWERFUL COMPUTER SOFTWARE. (Actually, it was just a Perl script with a
couple of calls to ImageMagick.)
To build your own Sonobe Earth, simply print and cut out the squares of origami paper and
follow the folding and assembly instructions on the next page.
