[[Image:SmoothLifeL.gif|framed|right|'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 give widely varying 'forms of life'. Since all parameters are real (floating point) numbers, sligh modification in parameters gives slight changes in life 'behaviour'. Some sets of parameters produces 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 (as shown on the picture). You can see 'cell' division, growth and decay.

It has been proposed that this page be moved to SmoothLife due to the following reason: Not a single rule but a family of rules; families of rules aren't usually in the OCA namespace.

'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 behavior. 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).

SmoothLife can be simulated in Ready.
