HWSS eats a somewhat complex still life; disappears entirely within 12x10 in 48 generations:

Code: Select all

``````x = 17, y = 14, rule = B3/S23
13b2o\$11bo4bo\$10bo\$10bo5bo\$10b6o4\$4b2o\$4b2o2\$2o2b4o\$o2bo2bo2bo\$2b2o4b
2o!
``````
EDIT! MWSS also eats it from the same position, albeit it happens in a larger bounding box and takes longer:

Code: Select all

``````x = 16, y = 14, rule = B3/S23
13bo\$11bo3bo\$10bo\$10bo4bo\$10b5o4\$4b2o\$4b2o2\$2o2b4o\$o2bo2bo2bo\$2b2o4b2o

This wick of length=1043 cells reaches the end of the wick after collision with a glider in 1043 generations, effectively carrying the information at c (a complex system to intercept the signal would have to be attached at the end though):

This gave me an idea for another forum game though: build onto and extend a structure that completely destroys itself.

As it stands, it's a stable constellation, but if you pick the right place to add a single cell, it will completely self-destruct in 904 ticks.

If anyone needs it, the location of the cell is hidden in the RLE in a fairly obvious way, that LifeViewer and Golly can't see (pun intended) without a little help from a human editor. Here's the original description:
A long time ago, dvgrn wrote:I was reminded that I wanted to check to see how easy it was to convert the average Herschel conduit into a clean-burning fuse. One horrible thought I had was a Game-of-Life equivalent of those mate-in-four chess problems that I always hated [just because the board positions generally seem so contrived, and it's usually easy to mate in five or six...] In this case it would be:

"Add one ON cell to the following pattern to produce an empty universe in less than 1000 generations."

Along those lines, here's some pseudorandom soup I just cooked up -- modified pieces of the first four conduits I tried.* It fails a number of randomness tests -- too many boats and long boats; I was using them to reflect gliders, but I should really have used larger random-looking constellations like the one on the lower right.

But I don't want to make this into an attractive-looking puzzle, for fear someone might like it and produce more of the darn things. Life is hard enough already.

It's obviously very easy to throw together miscellaneous debris that
can catalyze Herschel reactions. When I find an actual use for this
idea, you can be sure I'll post it --
...
* For the record, in order of use, the conduits are:
1. An R-to-Herschel converter
2. A Herschel transceiver
3. A 166-step conduit
4. A Herschel-to-4-glider converter [posted by Paul Callahan on 11 Nov 1996].
Luckily nobody encouraged me at the time, so no more similar puzzles were forthcoming. Eventually the idea evolved into Demonoid self-destruct circuitry... but now it looks like simeks' search program can do a much more efficient job of this kind of Seeding for Destruction, than I could ever manage.

I think I'll pass for now. That reaction moves the B-heptomino 13 spaces diagonally every 102 ticks, using up two synchronized gliders and spitting out two random gliders to the side.

Here's what I did to find out the period and offset, by the way -- color the original B white in LifeHistory, and then wait for it to reappear. It's pretty straightforward once you get used to it:

Code: Select all

To get started on an engineered spaceship, you generally need to have some hope of getting something for free -- more signals coming out than you have to put in. If you're just barely breaking even, you don't have any extra pieces to use to build your helices or whatever... there might be some sparks there that you could rub together by putting multiple B's next to each other, and get extra signals out, but it doesn't look too likely offhand.

It seems there is a solution with less than 20 gliders.

EDIT: The 3rd pattern demonstrates a solution with 19 gliders (16 for the base still life, 3 for the loaf).
