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 that has been known to occur naturally (the other being the block-laying switch engine).

Time bomb

The time bomb (shown below) is a 17-cell pattern that was found by Doug Petrie that evolves into a glider-producing switch engine.
