Hmm, not sure what locally Euclidean means. I would understand layouting 
the connections in a wheel around the focus as locally Euclidean... But 
you cannot build grids and cubes with it, that's true.

I guess I don't see it as that important. But we'll see, maybe you're right.

You have to be careful that the views don't step on the patent, then.

Note that we did it in Gzz because we couldn't do better. ZigZag does it 
differently.
