Recent finds from running barrister on the start of the speed tunnel:

top row: G-to-octomino, a few G-to-edgy-beehive (with the known one for comparison), and a G-to-2 blocks.

middle row: near misses on a stable reflector. Two where the glider crashes into a catalyst, and one where there's a block left behind.

bottom row: G-to-driftiness. Maybe a G-to-wire-signal with a bit more work.

Code: Select all

Some of these perhaps belong in a different thread, but I'd rather write 1 post instead of 3. I'm guessing one of those edgy beehives can be made into a Gn-to-H, so it fits well enough.
