Thanks everyone, I appreciate it
Very nice ... that's a lot of paper and patience to go through. Good for long car trips when you're not driving
What books did you find them in? I'm pretty sure I have one of them, or at least something similar.
A good number of the models come from the various books written by Japanese author Tomoko Fuse. She is one of the authorities on modular origami polyhedra as well as other sorts of things like box origami (you can see those at the very front of the picture). Others come from trying to imitate what I have seen on other websites or just from attempting to build a model of some of the various uniform polyhedra/duals. And I have actually made quite a few while in a back seat of a car...
They're beautiful! Are they your own patterns?
Although most came from Fuse's book, some of the bigger ones are variations on her patterns. Once you can make a basic unit, adding an extra crease in various places can transform the look of the unit significantly and change the resulting pattern. Also, she provides the units and the instructions for a basic shape such a stellated hexahedron, and I used the units to make something bigger, such as a stellated icosidodecahedron. Some of the larger shapes are not so structurally sound and tend to collapse in on themselves over time.
There is one that looks like a huge Alexander's Star what is that.
I'm not sure quite which one you are referring to. If you could try to point it out in the second picture where it's easier to see everything, I could tell you what it is.
