Since I'm on to animated transitions for my interactive skymap, animating rotations is the logical next step. Here is a live demo showing the effect along with some of the weirder projections possible with d3.js as in the last post. Only this time not as a video but with the animated map itself.
Starting with the not-so-weird Aitoff via Bonne, Foucaut, Ginzburg IX, Hill Eucyclic, L'Arrivée back to Aitoff.
