New sparky p14 shuttle found by carybe (again):

`x = 11, y = 15, rule = B3/S23`

It has exactly the same symmetry as the tumbler, and even looks a bit like a larger version of it. Isn't there some pond hassler wick that this could support? The oscillator looks like a semi-useful sparker, although p14 isn't too common of a period sparker to need. (I

knew I kept fruitlessly checking all those p14 census categories for years for a reason.)

Two soups so far:

`x = 16, y = 31, rule = B3/S23`

Both soups suggest possible syntheses, although of radically different types (L-tetromino+phi+blinker+block mirrored for the first, and disintegrating large SL plus blocks for the second).

EDIT: Also,

yet another p30 stabilization found by carybe, this time from D8_4:

Sadly, the fact that the ship forms at gen. 4 precludes the possibility of a synthesis arising from it.
