You can combine BMS symmetries and twistors into a BIG (infinite-dimensional) supersymmetry algebra.
Out now at a local arXiv near you: https://arxiv.org/abs/2112.07186
Neveu-Schwarz supersymmetries make a cameo appearance, and there is a post-credit scene with spin-weighted spherical harmonics and Wigner 3j symbols!
