What do you do with a broken set of blinds? ...

... assemble them into a geodesic sphere, of course!

Been working on this the last two days:

wow! Good Job Tangent!! Where'd you learn to do that?

Your math teacher must you. xD Excellent job, my friend.

Wow. That is sweet. Like Bucky Fuller.

I plan on showing it to her. My Calculus teacher isn't exactly the sort, though. I think my PreCalc teacher will be impressed, anyway- she likes following my projects.

I learned the geometry aspects online, though it turned out I could reuse a lot of the calculations from my old 3D Globe widget. It's actually pretty simple- take a Platonic solid, divide each face into smaller triangles, and stretch the new vertices out until they lie on the same sphere as the original vertices. I used an Octahedron, and divided the faces Triforce-style, but other ways work too.

My dad advised I drill holes and use pop rivets to connect them.

I then wrote a quick program to calculate the needed side lengths.
