I may be stretching the definition of algorithm here, but I've always been fascinated by signed distance functions / signed distance fields for 2D / 3D shapes.

Being able to do the full set of boolean operations on shapes with just `min` and `max` operations is pretty cool. Doubly so because boolean operations on standard geometry is such a difficult, messy problem.
