Usual (=Euclidean) billiard is physically motivated by a variational principle based on the length of cords. Replacing length by (symplectic) area leads to symplectic billiard. Through examples and pictures we will discuss first properties of and results for symplectic billiards for smooth curves as well as for polygons. Symplectic billiard has also a curious link to basic geometric approximation theory. Then we will see polygons on which symplectic billiards have surprising dynamical properties none of which are possible for Euclidean billiards. In the end I will present a theorem giving sufficient criteria for polygons to exhibit these dynamical properties. This is joint work with Sergei Tabachnikov, and Fabian Lander and Jannik Westermann.
