Windtree model

The windtree model is a billard in a non compact billiard table: the plane minus scatterers located at point of the lattice Z^2. Obstacles are identical rectangles. I will discuss dynamical properties of this system. I will focus on the link with Teichmueller dynamics with is a very active area of modern mathematics.
