Usually simply called an eater, and also called a
fishhook.
This eater can be constructed using a simple two-glider collision,
as shown in stamp collection. It is often modified in various
ways, or welded to other objects, to allow tighter packing of
circuits or to allow a signalstream to pass close by. See
clearance for an eater1 variant that is 1hd shorter to the
southeast than the standard fishhook form. An eater1 can also be
used as a 90-degree one-timeturner.
Its ability to eat various objects was discovered by Bill Gosper in
1971. The fishhook eater can consume a glider, a LWSS, and a
MWSS as shown below. It is not able to consume an HWSS, however.
See honey bit or killer toads for that.
Game of Life Explanation
The Game of Life is not your typical computer game. It is a cellular
automaton, and was invented by Cambridge mathematician John Conway.
This game became widely known when it was mentioned in an article
published by Scientific American in 1970. It consists of a grid of
cells which, based on a few mathematical rules, can live, die or
multiply. Depending on the initial conditions, the cells form various
patterns throughout the course of the game.
Rules
For a space that is populated:
Examples
Each cell with one or no neighbors dies, as if by solitude.
Each cell with four or more neighbors dies, as if by
overpopulation.
