While we’re on a nostalgia trip, this bears mentioning: a brand new, under development, NeXT-like desktop environment for Linux.
It’s based on CentOS (which is sad, since it severely limits the amount of people who can take immediate advantage of it and makes it a pain to, for instance, port it to the Raspberry Pi), but is nevertheless remarkable–I miss the NeXT UX (and its brutalist aesthetic), and would love to see a modern Linux desktop based on it.
Worth revisiting in a year or so.
