My Sonobe Jasmine Dodecahedron

Nov 29, 2011 05:48 AM

Here's my Sonobe Jasmine Dodecahedron built from Imatfaal's instructions.

Colorful geometric paper ball made of interwoven strips.

I built it using "cheap" patterned origami paper (150 cm so I could use Imatfaal's measurements) from Michael's.  I then took some silver metallic leafing paint and painted the exposed white parts with some overlap before putting the object together.  I must admit that I am not an origami purist.  I did not cut the slits.  I assembled the dodecahedron and then applied glue to each of the 30 vertices where the pentagons come together.  It is now a very solid model, with the unintended consequence of letting the centers of the pentagons be pushed into the model which I think looks really cool.  You can see that a little bit better in this video.

I also used the coloring scheme suggested in the post.  One thing that I found out that is cool about this scheme is that it actually ends up making the colors form a dodecahedrally distorted version of the 5 intersecting tetrahedra, with each color making up one of the tetrahedra.  This is really cool and so this is probably my favorite origami model now.  Thanks Imatfaal!

The next big software update for iPhone is coming sometime in April and will include a Food section in Apple News+, an easy-to-miss new Ambient Music app, Priority Notifications thanks to Apple Intelligence, and updates to apps like Mail, Photos, Podcasts, and Safari.
