Re: specialized compression

xlife did this with its #I format, see Life man page But as Dave says, it's not fun to write a parser to read or write such files. The other approach is to use a Python or perl script to build the pattern, and compress the script, an approach I've used with some of my Ticker patterns. Here's an exam...

Re: Golly scripts

Thanks for fixing that, Awesomeness. I'm still using Golly 1.2 on this ancient machine. I need to do major "renovations" before I can run later versions. So there are a few differences in the way scripts behave on my system. I don't know if this has been changed in later versions, but if you do a Py...

Re: Golly Logo / about us ticker tape?

I've uploaded a few Python scripts (in the Scripts forum) to produce patterns like this. And in the Patterns forum, I've posted pattern files that produce images of Marilyn Monroe and John Conway. They shouldn't be too hard to find. The Golly ticker (and my earlier scripts) use p46 technology, but t...

Re: General Musings: My Life Story

I, too, started playing with Life in the early 70s. In those days, I used modeling clay on the bathroom floor tiles.

Re: Spaceship speed limits

I spent some time last night playing with patterns like the ones Calcyman posted above, but with enough separation to allow the reactions to work properly. I now agree that the stargate's fast forward reaction (FFR) is an optical illusion. At step 6, the FFR produces a LWSS displaced 11 cells to the...

Re: Spaceship speed limits

A recent example was the reasonable explanation in the LifeWiki that the stargate was an optical illusion, but that leads to the interesting question of whether the stargate needs a steady stream of space ships to generate the boost, or if it can be done on demand? The stargate is a p60 device, and...
