You should be able to modify it by selecting different UV Mapping 
coordinates, unless you want a different shape than the torus.

If you use uv_vectors <0, 0>, Mid/2, <1, 0> on one triangle you get a 
strange swoop in one triangle (image attached).

If you want multiple torii in the triangle, you either need to define it 
that way or try warping the object texture, which I've never played with 
so I can't say it would work.
