For my 3d project I decided to make an origami icosahedron. It has twenty faces and was made of about thirty different modules.
I made the modules from a video on Youtube. The pieces of paper I used were 12in x 6in rectangles. Because the icosahedron was so large, I had to hold it together with tape before it was finished.
I chose the theme simplicity because the shape is a fairly simple geometric shape. I chose to use simple colors to emphasize simplicity.
