Toad.gif
Toad is a period 2 oscillator that was found by Simon Norton in May 1970. It is the second most common naturally-occurring oscillator, although blinkers occur more than a hundred times as frequently. It is also one of very few known oscillators that is a polyomino in one of its phases. Toads often appear in large, complex patterns because of their ability to eat things when paired together (as in killer toads). Additionally, toads are useful as building blocks for constructing large oscillators with periods that are a multiple of two because of the various ways in which they can be hassled.

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 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, half-bakery knightships are the only known types of spaceships with fixed slope but adjustable speed -- not counting 0E0P metacell-based patterns?
  • ... 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?
  • ... that several different patterns have been constructed to calculate and display the sequence of prime numbers, and some have been adapted to display only prime pairs or Fermat primes?
