Click on the headline to see an explanatory paragraph. (Terrible design. Why is it hidden?)

Also, there is a detailed explanation on the site here: http://hevea-project.fr/ENPageToreDossierDePresse.html

It's hidden behind a link labeled "Folder", which doesn't really make sense in English (it's a direct translation of French "dossier").

OK. I think I've got it. It's a way to map a 2D square to 3 dimensions without distorting distance. Is that right?

A simple torus mapping stretches distance in the x direction depending on whether you're on the inside or outside of the torus - and the wrinkles fix this.

(IANAM if that wasn't obvious)

I've read the explanation of the construction of the flat torus on TF-web-site. But I fail to see what kind of consequences this construction has. Does it open the way to new solutions to old problems, have practical applications or is it, for the moment, "just" a nice mathematical object ? (I'll be 100% satisfied with the later, it's incredibly mind bending)

Thanks. This should really be the featured link.
