A spark and its many uses: .. The spark is mentioned under Eater 1 in the wiki, but the rest of the transformations may or may not be new. I have no idea if any of it is useful or not, though.

In the instances you mentioned, a single point-wise bit-spark (or equivalent point-wise domino spark) would have the same effect. I am not sure how expensive the above-mentioned spark is (probably 3-4 gliders), but a point-wise domino can be made with 2 (with lots of junk that reaches as far up, so it has limited usefulness), or 3 in several ways that are formed more cleanly:

I suppose I only used that spark because of old habit from before I realized that a smaller spark could do the trick as well.

[mniemiec]

Yes, but can one of those sparks do this? ...

In this particular case, two of the two-glider ones could do his, although the single spark would win if it could be formed from just 3 gliders. Do you know of a way to do that? It seems likely that there should be some 3-glider collision that would make such a spark, but i don't know of any off hand. i don't have sparks categorized by that particular result (e.g.a 2x5 block with the middle row shifted forward one). I have seen that come up before, but I'm not sure how.

[praosylen]

I dunno, maybe a glider applied to the side of a B-heptomino could do the trick.

But, this fuse can be ignited very easily, and putting two or more trails near each other enables the reburning reaction to occur spontaneously. Unfortunately, most of the fuses die out eventually(especially when there aren't many trails). But some do successfully become reburners. Here is a dirty reburner with two trails.(It takes some time to stabilize.)

There is another impediment: the blinker is not relocated strictly diagonally, so the track wouldn't be reburnable even if there were no problem with the spark.

But I haven't seen that first block replaced by a B-heptomino before. The spark to the right is very small, so there's some hope that the pre-Herschel can be settled down into a block in the right location.

If we're very very lucky, Bellman (or 'catalyst' or 'ptbsearch') can rebuild the other block, resulting in a color-changing stable reflector. The Snark is color-preserving, so a completion of this would fill in a big hole in the stable circuitry toolkit, especially if it can be made into a G-to-H, or if it's made out of Spartan objects.

A G-to-H isn't as unlikely as it looks -- there's a lot of space to put a transparent junk object to move the reaction away from the danger zone, while restoring that second key block. Any given transparent object location is really really unlikely to work, of course... but you never know, it might be time for a lucky find in the Hunting of the (Color-Changing) Snark.

Huh, I don't recognize that one! Seems as if someone should have stumbled on it before, so I won't get my hopes up too far -- it's the same initial G+halfblockade reaction as Guam's 2G->H circuit from a few years ago, which was also used in a big old stable reflector of Paul Callahan's:

Thanks for the info! I guess it's a long shot, just what I expected when I wrote that post. Still, I'll try. (and I don't mind if anybody else tries.)
