Tread Observation

Earlier I was absently toying with the treads I posted about earlier while doing some studying, and I happened to find an interesting thing you can do with them. If you curve the treads backwards, you can make a circle out of them, where the insides of the links are facing outward:

So I was wondering if maybe this construction could be used for something like a giant wheel or gear (turntable?), since sprockets can mesh with the outer rim of the circle to rotate it. And since the links have peg holes in them, you can put supports inside the circle:

You can also use the peg holes to put an axle hole or something similar at the center of the circle, so it can attach to a robot (i.e. actually be useful :-) ).

Any ideas for how to use/improve something like this?
