edit hmm not sure how to format this on discourse but I spent too much time fiddling around in gimp to not post it :joy: click to expand and see the whole thing

its better to cut long image on separate images and post them like this:

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… :laughing: 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 :joy: :rofl:

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

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:
