Application developed by:

DESCRIPTION:
The
double torus begins as an octagon that is soon divided into two opposite and
equal shapes. In continuous scenes, one half of the octagon curls and closes forming
a torus with a slight opening on one side. The second half of the octagon, having gone through the same
mobius
transformation, appears from outside of the local environment and merges
to form what is known as the
Genus II Surface.
