Jagged lines is a pattern constructed by Dean Hickerson in May 2005 that uses puffers to produce a line of bi-blocks that weaves back and forth in a complicated way.

Also available: 38KB .zip archive containing approximately 75 pattern files for other cellular automata

Did you know...

  • ... that space nonfiller patterns have been constructed that expand to affect the entire Life plane, leaving an expanding region of vacuum at their center?
  • ... that there exist non-monotonic spaceships, even some with period as low as 3, whose leading edges fall back in at least one generation?
  • ... that some periodic objects -- e.g., a pentadecathlon hassled by period-7 pipsquirters or a 28P7.1 hassled by a mold -- can be perturbed to cause them to skip forward or fall behind by one or more phases in their cycle?
  • ... that more stable seed constellations for moving objects were completed in 2020 than in all preceding years put together?
  • ... that Don Woods developed the text adventure game Colossal Cave Adventure with Will Crowther, who was previously Dave Greene's father's roommate for a time at MIT?
  • ... that Rob's p16, with only 21 cells and fitting in a 9 × 8 bounding box, was only discovered via a large-scale apgsearch soup search in 2020?
  • ... that the minimum one-cell thick solid line that produces escaping gliders has 56 cells?
  • ... that the smallest known oscillators of period 3, 4, 8, and 15 all have exactly 12 cells?
  • ... that a solid 83 × 83 square produces four unices at the corners?
  • ... that a strictly volatile period-4 oscillator was not found until 2021, and the smallest known example contains a whopping 416 cells?
