Construction of sphere-filling ropes

The left movie shows the construction of $\beta^{6,i}, i=0,1,2,3,4,5,6$. Each of the curves has a thickness $\Theta_6=\sin\frac{\pi}{2\cdot6}$. The second and fifth curve are the only two one-component, closed, length maximizing curves of that thickness on the two-sphere. The second curve is blown up, to show, that the curve indeed fills the whole sphere. The other curves have more than one component but are as well sphere filling.
