People I work with recognize my computer easily:
it's the one with nothing but yellow windows and blue bars on the screen.
That's the text editor acme, written by Rob Pike for Plan 9 in the early 1990s.
Acme focuses entirely on the idea of text as user interface.
It's difficult to explain acme without seeing it, though, so I've put together
a screencast explaining the basics of acme and showing a brief programming session.
