Serenity: a new UNIX-like operating system

I always wondered what it would be like to write my own operating system, but I never took it seriously. Until now. I've grown tired of cutesy and condescending software that doesn't take itself or the user seriously. This is my effort to bring back the feeling of computing I once knew. Roughly speaking, the goal here is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by me, for me, based on the things I like. Seriously impressive work, as you can see in the demo video of the current state of the operating system.
