Portrait endless ripple wrapping. Colour balls drift on the water and touching the surface rings a ripple out from the finger; whichever ball the ring rolls over is wrapped and scores, and that ball bobs up again somewhere else. Deep brown silt vortices turn slowly in the water and keep widening, and a ripple that runs into one is swallowed whole, so where the ripple is rung from matters as much as when. Every ball wrapped drives the largest vortex back a little, and the run ends once the silt has taken most of the water. A ripple spread widens the rings noticeably for a while, and a clear barrier holds the vortices off the middle so they cannot close in. Endless mode with no fixed stage.
