I'm playing with the idea of making a mobius strip automaton. Any ideas how
one might mount such an arrangement?

Looks great.
Try two of the rollers fixed(non driven but with bearings) and just
drive the last one.

But you'd need some kind of a shaft passer mechanism in order for it to allow the full rotation.

Or maybe some kind of ring that rotates out of the way

Greg

this is a very nice one. I should be fun to fab it as a very large
sculpture.

Why not implementing it as pogo stick ... :-)

How about this one: http://forum.openscad.org/file/t622/ringading.gif
The outer blue races could be mounted solidly and the inner blue
construction would be forced to remain in place because there is always at
least 2 green rings in it.

Greg,

one of the three units would be enough. But in my eyes even then it will
have too much structure and loose its elegancy.

I think you'd need at least two rings, if you don't anchor the top and
bottom of this design, it just wouldn't work...

I'd be impressed enough to see a working design just to rotate a plain
torus shape in this manner...

Ok, here's another one. The ring bends up in the right moment.

Can you have a slot in the mobius band that is narrow enough that it still
goes through the rollers and then a thin support that the slot misses?
