MWSS version of the LWSS fast shifter for a glider:

$92bo4b2o12b2o$90b3o18b2o3$112b2o$97b2o13b2o$91b2o4b2o$91b2o!
```

The minimum shift for the MWSS version is just 5hd !

The minimum shift for the LWSS version is 19hd.

Shown at right are the missing 13hd and 15hd shifts to make a complete collection for any shift amount (using 5 blocks or less). Of course, any optimizations are welcome.

Unfortunately the MWSS version does not shift by even amounts of half diagonals, but it does handle shifts as small as 5hd.

Is there a way to use this as a seed to block a glider lane? I can see three different ways for the long hook to eat a glider or catch a boat-bit, but none of those glider lanes can

**quite** get past the two blocks in the seed...?

What's the most compact toolkit to produce either even- or odd-phase output gliders on demand, on either color of lane? The

toolkit I came up with for freeze-dried salvos works okay, more or less, and it only needs four different components, with two or three blocks each.

But for long salvos the duplicator chains have a slight tendency to drift to one side. And the output glider phase changes with every glider duplicator, and one of the duplicators is fairly big, slow, and awkward... In other words, it's a bit of a pain to use for manual constructions.

Probably I should just stop worrying about it and write a freeze-dry.py script to do the work of converting salvos into blocks. But is there a nicer toolkit I should start with?

As usual with posts consisting of nothing but code blocks with RLE, the above message is desperately in need of pattern comments and/or a little bit of text for future searchability.

Pattern #1: three blocks make a 180-degree one-time turner with a 6-lane offset.

Pattern #2: three blocks make a dirty OTT -- output is a 90-degree glider and a pulsar.

Alright then.

The first pattern is a 180 degree glider one time turner but also, the pattern interacted with the output glider twice and the second pattern is just a 90 degree glider and a pulsar. Don't forget, the code inside my signature is on topic.

See also the LifeWiki

turner article. This is the turner Seeds of Destruction uses for a 90-degree color-preserving turn.

There's another two-block OTT, also color-preserving, but it's a 180-degree turn.

I was just thinking about maybe there could be a blockic eater, but I'm not sure if a blockic eater might be possible, because there aren't that much reactions which can produce blocks, and only blocks.

Moosey

asked this question almost exactly a year ago, and the answers went through a lot of the possible variations.

A Blockic eater could certainly be constructed, but it would be a research project on a similar order of complexity to the Caterloopillar, or possibly the 0E0P metacell.

There might well be a much smaller, non-universal-constructor-based Blockic eater (or glider reflector, or glider splitter!) out there somewhere, but it would be a new mechanism. Without a long-running exhaustive search the odds of finding it are low, if it even actually exists at all.
