I'm sure there are ways of making the sparks from 3 gliders each, which would make this cost 12 gliders. I know I've seen them come up lots of times; I just don't have any listed in my collection that I can find.

`x = 14, y = 14, rule = B3/S23`

o!

I had already posted a synthesis of that oscillator on 04JUL 2015 (in the Synthesizing Oscillators thread), so you should already know about it:

However, this new method will likely turn out to be cheaper.

Also, a really interesting P4:

`x = 31, y = 31, rule = B3/S23`
