I discovered that a p30 Gosper Glider Gun can be used to invert a glider coming from the front:

Code: Select all

```
x = 36, y = 24, rule = B3/S23

```

I was firing said gun into a debris field. A glider came back towards the gun very close to the stream. I thought for sure the gun was done for and was amazed when the gun survived and a hole was left in the glider stream.

I tried pairing two p30s together. The reaction takes out two incoming gliders and one outgoing glider:

Code: Select all

```
x = 132, y = 114, rule = B3/S23

Trying to use it as a memory loop in the traditional way failed (It erased the information):

Code: Select all

```
x = 129, y = 108, rule = B3/S23

However, It does work as a memory loop to store groups of one or two gliders, with one empty space between each group (Distance between guns lengthened to better show that the memory is stored.):

Code: Select all

```
x = 170, y = 149, rule = B3/S23
