Perhaps a bit of a change from the previous comments, (sorry), but some things I have discovered or engineered.

1. A modified version of backrake 2 with an additional LWSS which interacts with the glider stream. The resulting pattern is both a puffer and a rake.

`x = 30, y = 55, rule = B3/S23`

2. MWSS and GLider collision producing a temporary switch engine. It lasts from generation 311 to 316 before it is destablized.

`x = 9, y = 10, rule = B3/S23`

2a. A modified version of the previous pattern that has 3 more gliders and produces a glider-producing switch-engine

`x = 90, y = 91, rule = B3/S23`

3. A 2 glider and MWSS interaction which yields a transient rare still life which I forget the name of. This still life appears at generation 2,406 and is disrupted at generation 2,486

`x = 7, y = 12, rule = B3/S23`

4. A couple of reactions between a glider and a spaceship which actually lengthen the spaceship!

`x = 30, y = 9, rule = B3/S23`

5. Other Reactions between a Xwss and a glider

`x = 153, y = 72, rule = B3/S23`
