Golly 1.2's hexadecimal counter
Engineered Objects
Version 1.2 of the cross-platform CA editor Golly was rolled out in mid-April. The main new feature is multiple layers that can be either stacked or tiled, showing either separate universes or multiple views of the same universe. Sample scripts envelope.py and heisenburp.py show possible ways to use this.
Among other additions to the pattern collection, updated versions of some of Stephen Silver's ships.zip archive from 2004 have been added to the /Spaceships folder. And Hashing-Examples now includes a two-digit hexadecimal counter using metapixel technology -- a 30K pattern file that encodes a 32768x20480 pattern with over two million ON cells:
Some more detail on the hex counter, with a series of screenshots at different scales, can be found in this weblog entry.
