aha i've been hacking away at the terminal graphics over ssh for ages for months, the repo is fully open source.

the sprites aren't all the same size or as good as they could be but already spent too much $$ on sprites.

the sprites are just passed through algorithms that optimize for what text characters at different aspects would make them look good.

I was pretty proud of my Game of Life & Wireworld implementations for the terminal, with half-character resolution o.o; Guess I'll have to up my game and start work on Twin Cobra and Dune ][ clones.. now that I've seen it's possible..

Using sprites is clever :-) then I guess that's how these older games worked too.
