Another model I started making nearly three years ago was a paper geodesic octahedron.

Or, if you please, a geodesic hexahedron (cube).

It's a dual model because the model is made up of forty-eight triangles and you can look at it as eight faces of six triangles (octahedron), or six faces of eight triangles (hexahedron/cube).

This was another pretty simple model to make, with the net taken from Vince Matsko. You'll need to print eight pages of that net, but there's a catch: you need to make half of the triangles "left-handed" and half of the triangles "right-handed" - folding the strips "inwards" for half, and "outwards" for the other half. If you want to make a two-colour model, as I have above, you'll need to make all the triangles of one colour left-handed, and all the triangles of the other colour right-handed. Again, I stuffed this up when I was making it, and so I've had to make two models - oops!

A little while ago (crap it was nearly three years ago!) I started building one of Vince Matsko's geodesic dodecahdrons out of paper, based on Magnus Wenninger's Spherical Models. I finished it a weekend ago (after realising I'd stuffed up when I started and was trying to do it with three colours, but it looks a lot better with four colours, so had to make the white pentagons as you see below).

It's a pretty straightforward model to build. Each pentagon face of the twelve faces of the dodecahdron is divided into five triangles, so you'll need sixty triangles. Vince Matsko's net has twenty per page, so you'll need three pages. Although if you want to make different colours like I have you may need more and have some leftover. When you fold each strip, the little tab will always be right in the middle of the group of five triangles. I stuck each group of five triangles together, giving me the twelve faces, then glued the twelve faces together into the ball.

A simple and fun little model to make.

After the Lego movie I went home to get my car and *stuff* then headed out to the club to meet up with the sweetie who went out earlier in the day.

We had the place to ourselves for most of it which was nice. Saturday afternoon I went for a wander around the perimeter.

It rained most of the weekend too, so the planned hazard reduction bonfire never went ahead. I cut and folded and glued little bits of paper.

I left Sunday morning to get a quick visit in to the Airport Open Day.

Just a stack more photos that still haven't made it online..

Add flocculent and wait a day for it to settle

So did some research, and stole a piece of four different coloured papers and a white and brought them home tonight.

Here's the old one and all the paper cut up. The ones on the right were the offcuts.

Four tetrahedrons..

And finally, five intersecting tetrahedrons!
