This week's featured article


Copperhead is a c/10 orthogonal spaceship discovered by zdr on March 5, 2016. The ship hauls a block behind it, which makes for interesting reactions involving other ships.

Simon Ekström found what appeared to be a tagalong with a large spark on March 20, 2016. However, the apparent tagalong actually temporarily interacts with the hauled block. The combined pattern is therefore generally considered to be a distinct spaceship, named fireship due to its unusual spark.

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 oscillator-supported conduits are included?
  • ... that Demonoids, caterloopillars, orthogonoids and half-bakery 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?
