Discover half yin-yang pattern by simulating kinematic motion using Linkage. To my surprise the setup is pretty simple; 2 same wide bar separated by same distance then add a diagonal linkage bar. One tip act as actuator while other tip anchored.

Tagging system proven to be flexible & reliable especially for synchronized complex motion.Some application; Teleporter portal tags, multiple instance range spotting, snake body segment chaining (pin or physics behavior).
Here sources for those cases:
I don’t know it was removed long time ago from Construct/Scirra arcade. Here the minesweeper clone is up again:

It’s really hard to make the chain behave correctly but hey it’s fun to watch.

‘Plus’ pattern consist of ‘brick’ objects summoned in 4 directions then advanced generates another ‘plus’ pattern with smaller repetition.
