It implies this edgy 4-glider synthesis, though I don't know if that's an improvement:

Actually that still life is already known to be constructible in four gliders, and the synthesis on Catagolue happens to have better clearance than your version (by constructing the traffic light in a more favorable direction).

I am not into the Game of Life so much but I accidentally discovered a pattern of 4 columns of 11 cells high, 2 cells wide and a distance of 2 cells.
After about 2300 generations it ends in a huge bo tie and contains blinkers and beacons.

I believe this works for all of the spaceships, unless it hits the lower snark, then you can adjust it if that happens

It's a slightly odd design, though. Here are the same pieces reassembled with the idea of getting the various signals where they need to go a bit faster -- 1834 ticks:

Trying to make an oscillator with Boats and Gliders,
I found a H-to-Boat to 180° Glider Reflector (if I can say) by omitting to delete the F117's input Herschel :

Code: Select all

x = 107, y = 76, rule = B3/S23

Here is just the H-to-Boat with/without the Glider in the right timing :

49bo!

Perhaps, it's already known
Otherwise, thanks to @Jormugant (to show me this H-to-boat).

Edit:
I know that my future oscillator will be a pseudo-oscillator, so it hasn't interest ...
Edit2:
And it is Spartan ... That's all folks !
Edit3:
Some corrections and comments.

H+G-->R (at gen. 42) :

Code: Select all

x = 30, y = 30, rule = B3/S23

Edit:
H+G --> Thunderbird :

I tried a boat catalysis and I thought it failed, except...it somehow made a come back!

Code: Select all

x = 5, y = 11, rule = B3/S23

A broken simkin glider gun creates a MWSS.

Code: Select all

x = 33, y = 13, rule = B3/S23
