Freeform optical surfaces are emerging as a path to truly three-dimensional optical designs. In this talk I will provide a short historical context to this emergence and discuss the challenges as well as the rapidly emerging knowledge that spans from the mathematics of freeform surfaces to the implementation of freeform optical systems.
