See Puzzle 4 for instructions. This being my first one of these in the new font, I figured I'd take the opportunity to also switch over to the Singularity template for the grid so that my suggestion of circling knights can actually be followed. Go figure.
Normally I'd never make a solving suggestion for a non-sample puzzle of mine, but I can't resist for this one: try to start with the center cell. It's illuminating. You don't have to - there are other break-ins - but that's where I started, and I daresay it's a pretty neat effect if you can find it. I'll leave the rest to the solver's own faculties as usual.
I'm currently wrapped up in making puzzles for a secret project, but I should have a batch to release here on my journal shortly thereafter. - ZM
