There are a few ways for the spark at the right hand side to turn a glider, meaning that an agar can be constructed:

Of course many other timings and phasings are possible.

Is there anything else that can be done with the spark?

[Rhombic]

What is (8,1)?

[HartmutHolzwart]

That's the direction in which the whole thing moves, i.e. 8 units to the left and 1 unit up in 63 generations.

[C28]

found a way to turn the spark on the right into a glider.

Code: Select all

x = 97, y = 111, rule = B3/S23

EDIT: turns out that the above is useless. this might be better.
