An eater is an object that temporarily gets deformed while altering an approaching blob. A rock is a special subset of eater that doesn't change while altering an approaching blob. A fishhook is most frequently used as an eater from the front, but it can also sometimes be used as a rock from behind. Blocks are frequently used as eaters (in queen bees and blockers), and occasionally as rocks. Blinkers, clocks, and toads are also sometimes used as rocks, when their pointy ends suppress sparks that would otherwise occur.

That looks very similar to a pattern discussed in Lifeline issue 10, page 7 (Harry J. Riley); however, your gliders are opposite direction.

I found these interesting 3 glider syntheses while looking for reactions for the stable line crosser:

Code: Select all

x = 58, y = 15, rule = B3/S23
11bo$11bobo$11b2o35b2o$b2o44bobo$obo46bo$2bo$56b2o$55b2o$57bo$8b2o$7bo
bo$9bo$41b3o$43bo$42bo!
The first one is almost symmetric, so it is surprising when a clean, asymmetrically-placed mango appears. The second synthesis creates a non-standard one-time reflector, as well as a perfectly placed glider that then reflects off it!

Technically it's not quite one-time. The R appears a long time before the block catalyst is destroyed, and escapes from the reaction envelope 16 ticks before that destruction. So at least theoretically, there's time to add more catalysts and rescue the signal:

Code: Select all

x = 20, y = 17, rule = LifeHistory

$7.2A!
#C [[ AUTOSTART THUMBNAIL THUMBSIZE 2 GPS 15 PAUSE 2 T 49 PAUSE 2 T 65 PAUSE 2 T 81 PAUSE 2 LOOP 82 ]]
In practice there are probably only a few ticks before that backspark has gone irretrievably out of control, though. I don't think any of the R-to-Xs in the current Elementary Conduits Collection can do anything with that R output.

The bigger problem is that you also have to get the LoM to that position in the first place. It would probably make more sense if people would come up with a half-decent source of LoMs before they bother to find all these converters that need LoM inputs. It kind of limits the usefulness of the conduit if the LoM has to be there at T=0 and there's no practical way to produce another one.

Some of the linked LoM-to-X converters allow the LoM to be produced by colliding two gliders, at least. That's expensive enough to make the whole exercise ultimately fairly pointless, but at least there's something. This latest LoM-to-R seems to have a block in the way of one or the other of those gliders, no matter which way you build the LoM.
