MATHEMATICS AND ORIGAMI

That ́s why the resultant figure requires a sort of frame to stay steady with a certain de-

gree of deformation.

If the produced deformation implies that both pencils in Fig. 2 become orthogonal, the

result is a sphere.

Fig. 7 is a wire-work view of the ellipsoid with its 14 cyclic circles. Fig. 8 is a perspec-

tive; in it, those cyclic circles look like ellipses just because of that perspective effect. In return

of that deformation we can gaze at the peculiar aspect of a hive-like structure.
