Prior art exists (brow.sh) but I wasn't satisfied with their graphical take. I wanted the raw, old skool terminal days of the early internet - BBS, and old green phosphor library comptuers - but running the modern web, with all the bells and jingle jangle whistles (JavaScript, etc).
No funding, no VC, just 100% raw terminal fun. Not sure how long the demo will last, but try it out.
