Short intro to phase spaces in dynamical billiards followed by 6000 points confined to the interior of a moose-shaped contour moving in a superellipse billiard (x^2 + y^2/b^2 = 1).

Music by @gpcbass. It's a remake of Joni Mitchells song Both Sides Now from 1966. Retrobites (gpcbass' band) version can be enjoyed here: youtube.com/watch?v=ChBU3O9MxAQ
