Houdini - Differential Curve Contraction (scene file)
Back when I was playing around with the POP based differential curve setups, I tried to get a contracting curve going using point deletion, but failed miserably. Seems I over complicated it, it's as simple as forcing the curve in a direction (in this example using positional noise as a force) and the continuous resampling will take care of reducing the points. Because of course it will. :D
