Spacelike CMC Surface with Swallowtails and Cuspidal Crosscaps

Four partial plots of a surface containing infinitely many swallowtail and cuspidal crosscap singularities. Produced by the solution of the singular Björling problem with Björling data $s(x)=\cos(x)$, $t(x)=\sin(x)$ and $\theta^\prime(x)=0.01$. The first three images are scaled by several factors in the normal direction. The 4th image is the same plot as the 3rd image, without scaling.
