An eater is any still life that has the ability to interact with certain patterns without suffering any permanent damage. The term may also sometimes specifically refer to eater 1, a very common and wellknown eater. The block was the first known eater, being found to be capable of eating beehives from a queen bee, allowing the construction of the queen bee shuttle. The animation to the right shows an eater 5 feasting on an incoming stream of gliders.
Eaters are extremely important, as they help stabilize and control debris created by complex reactions, allowing for the manipulation of the useful parts of those reactions. Stable reflectors in particular heavily rely on a variety of eaters to work.

Pattern collection

The LifeWiki contains one of the most comprehensive catalogues of patterns available on the internet. Within it you will find:


Did you know...

 ... that the smallest known spacefiller pattern consists of 187 cells?
 ... that the smallest known sawtooth pattern in Conway's Life consists of only 177 ON cells?
 ... that there are now over a hundred and twenty known Herschel conduits, counting stable conduits only, and a much larger number if oscillatorsupported conduits are included?
 ... that Demonoids, caterloopillars, orthogonoids and halfbakery knightships are the only known types of spaceships with fixed slope but adjustable speed?
 ... that a pattern exists in which no cell in the unbounded Life plane ever becomes periodic?
 ... that several candidate universal constructors have been demonstrated in Conway’s Life, but as of June 2015 none have been formally proven to be universal?
 ... that there are dozens of known Cordership variants, including puffers, rakes and wickstretchers, with periods of any multiple of 96?
 ... that greyships have been constructed with speeds of c/2, c/3, c/4, c/5 and 2c/5?
 ... that most greyships travel parallel to the stripes in their included agars, but a few travel perpendicular to the stripes, or "against the grain"?
 ... that a pattern has been constructed that calculates and prints out the digits of pi in decimal, and a similar one prints out the decimal digits of the Golden Ratio?
