The instructions seem rather sparse, like the Archimedean solids only have folding nets, and not the folding instructions that produce the cool looking pictures with the holes in the faces.

Even for the intersecting tetrahedra where instructions are available, I see that it's basically constructing the edges from 30 pieces of paper and then assembling them together. I wish they have more things that were built from a single square piece of paper.

It's definitely disappointing and feels like a lazy site to not have much more than "look at these neat origami representations of these shapes.

Building from a single sheet is pretty limiting and beyond a cube build like the classic inflatable lantern you'd likely need glue to hold the folds down I think.
