It's unclear to me why I'd want to use this over libcaca or similar? The demoscene has made really excellent ASCII rendering for decades, and this seems like it has less options and less understandable output. If this is just a fun personal project "just because" then cool! That's awesome! But for actual use cases I'd much rather use libcaca.
