Re: Refactoring DRH's cyclotron with stable components?

Single-engine cyclotron gun using the 3-block shifter+3 Snark reflector, no rectifiers needed: rle The key here was that, even though the clearance of the 3-block shift reaction gets compromised by the Snark loop, there's still plenty of space before those Snarks to fit an eater in.

block-laying circuit that blocks transparent lanes in two directions
