It looks like you have done a lot of work with sixels based on your github too. Have you ever written anything about that?
No, WYSIWYG: I don't bother much more than that with explaining how it's done: the source code + the comments + the github page already give all the details away to whoever wants to dig deeper.
I'm not much into social media or self promotion either: if people like what I do, they'll use it - I don't care much more than that, as everything was written for myself and my selfish needs first.
The tty/sixel world is very small world anyway, we generally know and recognize eachother, so we know where to look for cool new stuff :)
To be fair it was more like a joint venture between us!
