Re: Golly scripts

That toroidal script looks intriguing, Nathaniel; I'll have to check it out. I realize it won't be very fast, but it's nice to be able to do such things in Golly, since it's my favourite Life program for the PC. (Although from a user interface POV, Golly is still not quite as good as my favourite Am...

Herschel conduits and other stable circuits

After seeing Calcyman's intriguing patterns, I've finally started playing with Herschel based patterns. Here are a couple of my first efforts, cobbled together from parts scavanged from various places. Also see the scripts sub-forum for a Golly script that simplifies the construction of Herschel con...

A twin glider block puller consuming blocks laid down by a block-laying Switch Engine.

This script saves a sequence of generations in pbm ASCII format. Thus it can be used to create animations of Life patterns. It's just a minor variation of the SavePBM script I posted previously. Some display programs don't handle this format properly, but it can be converted to other formats like pn...

Re: Natural spaceships beyond the glider and *WSS's ?

I find that the larger the pattern, the more likely intractible graphing & plotting probs will give me grief. Patterns can get fouled (can't be repaired, errors out of control...) especially if the graph paper has very small resolution. I work best at 10 squares/inch. You spoke to me earlier,'bout ...

Re: Census Program Idea

Re: Glider circuits: components and contraptions

Glider grid collisions. Some simple still-lifes can be synthesized with two gliders. It's possible to create square grids of any size of these objects by colliding two grids of gliders.

Here's my first attempt at constructing a slow rake. It uses the well-known T-tetromino reaction. It generates a new glider every 64 generations. It's not very compact, but I think it looks kinda cute. :) This pattern uses two rakes, combining the gliders using the kickback reaction to produce a rak...

This patterns uses a pair of p240 glider salvo guns to shift a central block back and forth. Each salvo consists of 5 closely spaced gliders. Four of these glider shift a block by (14, 1), i.e. 14 cells horizontally, 1 cell vertically. The reaction also sends a glider back upstream, so an extra glid...

1. The golly.randfill() Python function doesn't seem to use a different seed each time Golly loads, and I can't seem to find a way to enforce a new one.
