It is possible to fold a cube from a single sheet. The cube on the page is made from several units. The method for folding a cube from a single sheet was independently invented by Kazou Haga, Kunihiko Kasahara, Jeannine Mosely, me, and probably some others as well.

It should probably be noted somewhere that this is more "papercraft" than "origami", and the thing you download is just the net of the solid, not instructions to make what's in the picture.
Also saddened by the lack of Catalan solids

Kusudama is your keyword if you want to learn how to do these :)
The 5 intersecting tetrahedra is particularly cool, and I've used these instructions to assemble it http://origametry.net/fit.html

I was lucky enough to meet the guy behind mathigon for dinner a long time ago. He's brilliant! I'm always excited to see what he is up to! Glad to see this voted up.
