Re: Smaller Pi Calculator Challenge

Ideally what seems to be needed is a cheap seed constellation that, when hit by a glider, directly returns a 180-degree glider, or two 180-degree gliders if some still life is present off to the side on the binary tape. Does the constant-return glider even need to emerge in the same reaction as the...

Sweeeeeeeeeet.
