Geonests

lately I've been thinking about how to make geometry more fun and interactive for all ages. and it hit me whats more fun for all ages then swinging and relaxing? 

so I started making a huge ball of geometry much bigger then anything I have ever made.

The first 6 pentagons of the icosadodecahedron

by making pentagons that tack together at the corners they naturally form the angles to make the icosadodecahedron. Its a mixture of pentagons and triangles

This was the foundation for the geonest ball chair.  I knew the pentagons were too big and open to support the cushion so I needed to fill them in. So I made 5 pointed stars to fit in the pentagons 

 The 5 pointed star in front and using the pentagon on the table to make the next one.

after a week of welding stars in it took on a new epcot ball shape. Now that it is made out of triangles its super strong. All it needed was a way in...

I had a 5/8 rod rolled into a hoop to make a porthole on the side of the geonest. Then I cut the rods where the hoop would intersect and tacked it in

Then I welded the porthole in solid and I added some bracing rods to the hoop to fill in spaces and add support. I knew it was very solid and strong enough to hold a lot of weight.  But I needed to know that all the weight wouldn't just be supported by one joint on top.  So I made a big 5 pointed star to go over the top and support the weight from 5 points around the top.
