The first one is one I did for an algebra class two years ago. I forget what I was studying, but I had fun doing the project. It's pretty simple, just a bunch of triangles folded together. One of my classmates wanted to use it as a soccer ball...he's lucky he didn't!
So here it is:

And my second one is one I did for my biology class last year. We were studying viruses and bacteria, so for extra credit I decided to make a model of a polyhedral shaped virus, observe certain patterns in the paper and its colors, and tell how my evidence supported the theory of intelligent design (creation/evolution controversy). This one was a lot harder to figure out than the last one. The pattern was a lot more complicated than I expected. But in the end it was well worth the work.
So here it is(to be exact, its 20 sided, so that means it's called an icosahedron):

For both of these I got the instructions out of a book called "Modular Origami Polyhedra" The first one is made of 20 modules, and the second is of 30 modules (30 pieces of paper for a 20 sided ball? that's wierd.) They require NO tape to stay together, even when you pick them up. Isn't that cool? By the way, the little numbers on the vertices of the second ball are there so that I could distinguish the pattern of colors. I ended up drawing a chart; it just got too confusing.
Anyways, I hope you like em!
