Folding a cube???
Found this at Math Recreations by Dan MacKinnon. Fold a cube into..well,some interesting stuff. The origninal work comes from Eric Demaine click here, then wait, it takes a minute to animate...but well worth it.

Hey Mr. Ballew!
Looks like I'm stalking you on this blog spot, haha.
They have this video playing in the background while they're talking with Erik Demaine in the new documentary Between the Folds: http://www.pbs.org/independentlens/between-the-folds/

The program is worth watching, by the way.

Very nice...I wonder how much of this I could construct in Cabri3D? I guess I know what I will be doing over my break.
Steve, share what you find... I would be curious about other ways to do this in the classroom (I'm sort of a Geogebra anf Geom. Sketchpad kind of guy
You asked, Pat. Here is my first attempt at creating one of the folded cube shapes:

This was all guess-and-check. I would like to work out the correct dihedral angles. I am not sure what I would do with this in class.
