Want spark/smoke patterns

[furrypony]

Basically I want to make an art with GoL. It would start seemingly random, then suddenly a picture emerges for one tick, then falls back to chaos again.
The original idea is to just draw the picture, then find its predecessor until I reach a predecessor that looks random enough, then run it. But I found out that reversing GoL is very difficult.
My second plan is to get a bunch of small patterns that fill the canvas. Put the smokes and sparks into the places that are left blank, and put some small predecessors of short line segments at the places that would emerge as line segments in the picture. Then the smoke would clear at the exact moment the lines become line segments.

So, do you have collections of sparks? I can't find many sparks on Life Wiki. Collections of predecessors of short line segments would also be welcome, though I could try to generate some for myself by the atavisers I've already found.

Something like this?

You can easily find ancestors of an arbitrary pattern with WLS (JLS, lifesrc) - unless it is a garden of Eden.

Thanks, just adapting that slightly gave me this:

I like "synthesizing" things by placing these sparks next to each other such that they don't interact until they reach their maximum size.

I also found this, which is weird because it kind of looks like it should be stable.

It CAN be made stable:

Looks like it won't end up being a very compact rake, though.
