This is super simple, but with how recent the speed tunnel is, I'm not sure if someone has noticed it before. Here's G-to-block, such that a second glider on the same lane deletes the block. It's also just barely edgy enough to be read by a glider traveling along the opposite diagonal. Seems like ...

This can be considered a block factory that just so happens to have an extra Herschel output:

New simpler mechanism. Without any resets it's almost the same population as the waterbear. Virtually any improvement will make it the new smallest.

This “P435 slide gun using a beehive” is the first pattern I’m sharing. And it is also the largest among the patterns I have made. (Each glider gun is a combination of the smallest P435 glider gun, Speed Tunnel, and Fx119 inserter.)

You can't daisy chain them.


The wiki has precisely zero matches for the word “daisy”, let alone “daisy chain”. So I’ll just assume you mean that since there are gliders in the crawler, you can’t just extend the crawler by placing the gliders with the same relative shift to the B ...
