Yes, that's a strange omission -- there's a perfectly good "crystal" entry in the Life Lexicon. Stephen Silver's original Lexicon site seems to be down at the moment, but there are lots of copies around, including in Golly. Crystals are mentioned in the 26-cell quadratic growth LifeWiki entry.gmc_nxtman wrote:It's called a crystal. By the way, there should be a wiki page on crystals.Hdjensofjfnen wrote:At the initialization area of this ark, a pattern of honey farms begins...
Crystals have been known and used since the very early days -- as soon as someone invented a p90 glider gun, probably, since they're a common nemesis of slower even-period glider guns firing into random junk. They also can be tamed to produce very high-period glider guns with a relatively small bounding box.
Here's a way to use crystals to make a large filled area with stable objects, as opposed to the colliding spaceships used in Brice Due's metapixel:
Code: Select all
#C Liquid-crystal metapixel display sample --
#C two p2^N guns turn extensible rows of half-beehives ON and OFF.
#C One cycle takes 262,144 ticks; Golly/hashlife strongly recommended!
