Some small things.

Oscillators:
x = 10, y = 10, rule = B2ik4567/S02i3q4567
$4bo$4b3o$2b4o$2b5o$b5o$b6o$b5o$2b3o$4bo!

x = 5, y = 6, rule = B2ik3/S2a3
$bo$b3o$3o$2bo!

x = 4, y = 4, rule = B2ik3/S2a3
bo$o2bo$o2bo$2bo!

x = 4, y = 4, rule = B3/S2ai3-e4
2bo$bobo$b3o!

Spaceships:

x = 4, y ...

So this rule has a very common spaceship:
x = 3, y = 5, rule = B3-q4-aiq5-i67c8/S2a34qwz5i
3o$3o$bo2$bo!

And in this rule you have a gun:
x = 7, y = 6, rule = B3-q4-aiq5-i6/S2a35i
$2b3o$2b3o$b5o!
This may be actually less interesting than I had thought. Anyway,

x = 6, y = 23, rule = B3-q4 ...

The ship also reverses its direction if it hits this oscillator:
x = 28, y = 3, rule = B3-q4-aiq5-i67c8/S2a34qwz5i
bo14bobo6bo$bobo11b2obo6bobo$bo14bobo6bo!


It can also destroy the oscillator and reverse its own direction:

x = 11, y = 18, rule = B3-q4-aiq5-i67c8/S2a34qwz5i
3$4b3o2$4b3o$5bo8 ...

So this rule has a very common spaceship:
x = 3, y = 5, rule = B3-q4-aiq5-i67c8/S2a34qwz5i
3o$3o$bo2$bo!
When two such ships collide, they reverse their directions:

x = 33, y = 5, rule = B3-q4-aiq5-i67c8/S2a34qwz5i
$5bobo13bobo$5bob2o11b2obo$5bobo13bobo!

The ship also reverses its direction if ...

A pretty simple blinker puffer:
x = 2, y = 3, rule = B34c6/S2-e34c5
o$2o$o!


A dirty rake and a kinda weird spaceship:

x = 11, y = 13, rule = B2e3i4/S2-a3
8bo$8bo$8bo3$6bo3bo$6bo3bo$6bo3bo$6b2ob2o$7b3o$3o$obo$bo!


x = 21, y = 10, rule = B2e3i4/S2-a3
