'SmoothLifeL' set of parameters

SmoothLife is a family of rules created by Stephan Rafler. It was designed as a continuous version of Conway's Game of Life, using floating point values instead of integers.

Different sets of parameters can produce a wide variety of life forms. Since all parameters are real (floating point) numbers, a slight modification in parameters produces a slight change in object behaviour. Some sets of parameters produce many interesting phenomena, such as gliders that can travel in any direction, rotating pairs of gliders, wickstretchers and the appearance of elastic tension in the cords that join the blobs (see picture).
