the 2-d model @ 45°

In the next model, we can see the same shape, turned to a 45° angle from its previous depiction, and given form extending into an additional dimension. This is also how time works: it adds spin in a fourth direction whose change can be measured as the dimension of duration. By adding an extra dimension to the simple circle, we produce the sphere seen here, with a clockwise spiralling top pole and a counter-clockwise spiraling bottom pole.
