This artwork depicts water ripples on a lake that is set in a typical Austrian landscape. The motivation behind it is the curve shortening flow, a geometric PDE, that transforms planar curves by moving each point in the direction of its curvature vector. In particular, a circle shrinks to a smaller and smaller circle and eventually becomes a point. This motif of concentric circles reminds me of the ripples in water when dropping a pebble into a still body of water, although in that case the waves spread outwards. Both processes illustrate the gradual and continuous change in nature.
