This is great, I've been working on something that tries to do something similar among other things. ANSI's going to come back in a big way - I got a hunch!
Here's what I made, but I'm keeping it stealth this month. I did make an editor/Converter, it's not great, but it makes ANSI's, and 256 colors as well. It's what I did with those ANSI's that's interesting - I stored them in the blockchain as non-fungible and created a neural network based off them. It's done, it's coming. Just don't want it all to come too fast.
