edit hmm not sure how to format this on discourse but I spent too much time fiddling around in gimp to not post it 
click to expand and see the whole thing
How are there not more Babadook baduk memes
its better to cut long image on separate images and post them like this:
[image1]
[image2]
[image3]
…
With apologies to とろろ
Context for anyone who has no idea what this is about
I’m sorry I think these are pretty inane… 
but after rewatching Tenet this weekend now that it’s on HBO max, and also playing 5D Chess I had to get them out of my system 
Tenet Go looks like:
black stone placed, white stone removes, black stone placed, white stone removes …
so if you replay game backwards, it looks like white stone placed, black stone removes, white stone placed, black stone removes
and endgame (fuseki) will look like 9 stones handicap game
prototype v2:
on each move it should look like move is logical in current position, in both time directions
…hard to create
Hahaha
From the very interesting video Props for Male Roles - YouTube which is part of a Japanese series on kabuki theatre.

Great job!
My most-liked post (29), by the way, is still this (from 2021 R. & R. adjustments):
My other two Good Reply badges are from here, though.
I just got my third and fourth Good Replies in the space of two hours :3
The latter was for perhaps my favourite of all my memes, now almost two years old:
