Given a singularity with a crepant resolution, a symmetry of the derived
category of coherent sheaves on the resolution may often be constructed
using the formalism of spherical functors. I will introduce this, and
new work (arXiv:2409.19555) on general constructions of such symmetries
for hypersurface singularities. This builds on previous results with
Segal, and is inspired by work of Bodzenta-Bondal.
