[Rulestring] 23/37 [Name] DryLife [Description] 
An exploding rule closely related to Conway's Life, named after the fact that the standard spaceships bigger than the glider do not function in the rule. Has a small puffer based on the R-pentomino, which resembles the switch engine in the possibility of combining several to form a spaceship.
