And here's one of the owners explanation of the project:
"Hey guys, thanks for the compliments. I've been meaning to do a photo tutorial of the origami but have been busy lately. Here's a rough explanation.
1. You'll need high quality poster board. I bought mine from staples for about a dollar per sheet. The larger it is, the better, as you will have to join less pieces of paper together.
2. Using a t-square and a 30-60-90 triangle, draw an equilateral triangle grid on the BACK of the paper. Go over these lines again with a straight ruler and a scalpel, and score them lightly.
3. Bend all folds inwards and outwards. If you only crease in one direction, the paper will not move freely.
4. Ideally, you can just do the same thing to the second piece of posterboard and hope that the two pieces line up well. Most likely, this won't happen unless you were incredibly precise in your triangle measurements. To account for this, after you cut and fold the first piece, line it up with the second unfolded piece of posterboard, and measure the distances between triangles. Use the 30-60-90 triangle to complete the rest of the grid.
5. Joining the two pieces is a complete pain. Use strips of paper and glue on the back. I originally used duct tape and it would tear apart at the seams and looked very unclean.
6. To maintain the shape, you'll need to compress the triangles and use long pieces of posterboard to hold them in place. Glue will work better than duct tape in the long run.
7. Take any left over posterboard and roll it into a thick tube. build a truss system at the back and secure the origami to this, as it will not have the strength to hold itself up. At this point you can attach strings to the truss and secure that to screws in the wall.
Overall, it cost only $5 per tessellation, but it took forever to find a reliable way to join two pieces of posterboard. This was a quick explanation, but I may have a more detailed one in the future.
thanks again."
