If there's a convenient way of putting the R-pentomino there with other technology, this might be something. As it stands, it's a curiosity.

The possible answer to a periodic Herschel splitter...

The original source is hard to track down, but this was investigated over a decade ago. Here's a gun by David Eppstein from 2003, using a previously-known p5 Herschel splitter:

When Bellman came out, I looked at this again to see if it might be possible to invent a custom still life to take the place of the spark. It seems vaguely theoretically possible, but it would have to take a very long time to recover completely, since it has to interact again around T=60 to suppress an R-pentomino -- I didn't see how to run any kind of reasonable search. Was I maybe being too pessimistic?

I found this new variant of the p30 pre-pulsar hassler while experimenting with modifying Bellman to add symmetry constraints: ...

If you alter the casing slightly so there are two inducting Es/bi-tables (giving this fourfold symmetry), this looks like it could even be fairly easily glider-constructible.

A reaction between a loaf and a TL may lead to a p20 oscillator:

Code: Select all

x = 27, y = 14, rule = LifeHistory

4.2D2CD13.2A$5.4D3.D$7.D3.3D$12.D$4.D$3.3D$4.D!

To spin the loaf, place the cross it faces.
However, there's a drawback which will be likely to clot the oscillator period.
I name: the remaining blinkers.
I found no 1-glider reaction giving enough blunt to destroy everything. And no 1-WSS neither.

Therefore, we'll need a lot of generations to reboot a quarter: At least 20 to destroy the blinks, and 20 others to trigger the light.
All that, hoping that the restarters don't interact.

A reaction between a loaf and a TL may lead to a p20 oscillator...

I couldn't get it to work at period 20, but it does work at period 24:

Code: Select all

x = 50, y = 50, rule = B3/S23

There is still a possibility that it works at period 20 based on this reaction, but someone would need to find a less obtrusive p5 volcano:

Hmm... sure, I hadn't seen the problem this way, yet to tell the truth I wasn't even aware of the existence of such a pattern...

But I noticed a few things.
1. As the loaf is symmetrical, it can spin in both way, creating a... uh... loafhalflipflop?
2. furthermore, a combination between guns and volcanoes, as you call them, may lead to a pattern where the loaf goes to 180° or 270°, and then goes back to start without doing a full turn. However, this would be challenging, as we would need cornershooters and possibly need to sacrifice a volcano
2.5 EDIT: Hey no! Such a reaction actually pulls the loaf. However, it means that it could be used as the back of a 2c/x spaceship, working in a way not unlike the weekender, but backward.
... And the back of a spacship is always a challenge, right?
3. Hey, a new (?) rotor needs a new name. What about lightspin/lightflip/trafflip/loafspin?
