Surface/Structure/Fold

Elijah Porter, a student at the Yale School of Architecture, has a great Flickr set up called Material Formation in Design. It features several awesome examples of how strategic cutting can transform a solid surface into a porous structure.
In the specific case of the image featured above, you're looking at what might be called subtractive origami, wherein diamond-shaped cuts have introduced foldability and mesh into a solid sheet of steel.
How interesting to think that, with just the right geometry of cuts and slices, you could activate the otherwise overlooked – or even unknown – baroque possibilities of a given material. You could even hold annual slice-design competitions, where students and mathematicians from around the world get together to display their secrets of cutting; one at a time, they program precise geometries into a laser-cutting machine, and whoever thereby achieves the most complex form, or the largest volume of folded space, wins.
Huge, 8' x 8' sheets of steel are turned into spheres and waveforms, in a kind of arabesque of wounding through which metal becomes lace.
One year, a student from Amsterdam blows everyone away by introducing just one, incredibly complex cut... and the whole sheet rolls up to the size of a one-inch ball.
Or you obtain a truck-mounted laser and a grant from the Graham Foundation, and you proceed to cut a new, gridded faultwork into the bedrock of the continent – perforation on the scale of whole landscapes – so that the geography you're standing on simply folds up and disappears.
