The glider-producing switch engine (or glider-making switch engine) is a puffer that was found by Charles Corderman in the early 1970's. It consists of a switch engine reacting with blocks to produce various still lifes and a glider every 384 generations. It is the second most common naturally-occurring pattern that exhibits infinite growth, and is one of only two patterns that exhibits infinite growth (excluding interacting pairs of switch engines) that has been known to occur naturally (the other being the block-laying switch engine).
