Minetest Mesecons Counter with 3-Phase Flip-Flops

The 3-Phase flip flop is my own design.
The first iteration has it's clock signal go from left to middle to right, whereas the latest design has it's clock signals go from middle to left to right.
The output signal from the previous flip-flop is used to and gate the left and middle clock signals going to the next flip-flop. This way each next flip-flop is chained to react to the previous flip-flop instead of every clocksignal.
This design only uses logic gates and wire, no movestones or pistons, nor any timing trickery, only pure logic with gates switching state.
I don't like weird trickery relying on timing things just right, and I dislike weird piston things which are not logic gates.
There are ways to do flip-flops with such trickery which don't require multiple clock signals, but since I disapprove of such designs, here is a 3-phase logic-only flip-flop binary counter in Minetest with Mesecons.
