Really interesting! Not sure what practical use it might have that differs from a more typical sparker — the spark isn't really robust enough to be likely to withstand multiple interactions. I would imagine this to be the first of its class, at least at low-to-medium period — hopefully not the last! As a side note, the rightmost segment of the rotor can be stabilized on its own, making a fairly small billiard table which may or may not be known: Code: Select all x = 16, y = 10, rule = B3/S23 10b2o$6b2o2bo$5bo2bobo3b2o$5bobobob2o2bo$3b2o4bobob2o$2bo2b2obo$bobo2b ob3o$o2b2o2bo6b2o$2o6b3obo2bo$10bob2o!

That's present in jslife's o0007-bil.lif, and I actually selected that completion manually after a certain point in the search.

It seems that the oscilliator must be known, but I'm unable to find it in previous collections.
For some strange reason it doesn't seem to be in jslife or the jslife-osc-supplement, but it is in DRH-oscillators (Golly Patterns/Life/Oscillators/DRH-oscillators.rle)
The latest version of the 5S Project contains over 226,000 spaceships. There is also a GitHub mirror of the collection. Tabulated pages up to period 160 (out of date) are available on the LifeWiki.

Please post this in a relevant thread, for example Thread for basic questions. If you can't get the Python script posted above to work, there's actually a Lua script that comes with Golly which you can find at Scripts/Lua/giffer.lua, which should work assuming your version of Golly is up-to-date.

EDIT: Please also read the forum rules; if you need to follow up on your previous post in a topic it's generally better to edit your original post rather than making a new one.

Bullet51 found a stationary fencepost for the other side of this wick in 2016 (see here). I know that Josh Ball (velcrorex) has found some interesting fenceposts to various wicks over the last decade, but I don't have immediate references.

Cross-posting from here, a Rich's p16 on tumbler is a 50p112 (note gen 46):

This mechanism can work with any period 9 or higher oscillator with a sufficiently remote domino spark. It works for pentadecathlons, and also snackers. Oddly, it does NOT work for tetradecathlons, because the phase-shifting process intrudes on the reaction.
A for awesome wrote:Nice! This other mechanism (previously known for pentadecathlons) works as well: ...
This should also work with any period 5 or higher oscillator with a sufficiently remote domino spark. It works for pentadecathlons, snackers, and tetradecathlons, but not fumaroles or heavyweight volcanoes. Some of the large P5 or higher domino sparkers might work.
