Yesterday on Puzzling Stack Exchange, I encountered this CA question about a curious Life variant: Cells are born as standard CGOL, but each tick that they remain alive they alternate between S23 (young, yellow) and S3 (old, orange).

Code: Select all
x = 148, y = 69, rule = LifeHistory
block-laying circuit that blocks transparent lanes in two directions

Sadly, passing a signal while the block is present causes an explosion.
