comment Tori in three-space
Yes. You can make non-geodesic elastic curves in the 2-sphere which oscillate around a great circle. They have enclosed area which is equal to the area of the hemisphere, but the lenght is strictly greater than the lenght of the great circle. Thus, Pinkall's formula for the conformal type implies, that you obtain a rhombic, non-square torus. The existence of these elastic curves follows from theorem 3 in arxiv.1303.1445.
