I'm working on COBRA: Not an 'OS' but a GUI, or Graphic User Interface. I'm working on it now. It will eventually have several applications, but when I release the demo hopefully later today, I'll just be showing off the base. And maybe have a file save/load system programmed, if I have time.
No more 'logging in' or 'booting up'.
A simple GUI made in Scratch, with save/load capability, great graphics, and maybe the ability to run 3rd-party apps, right in Java, is coming.
*IceOS, beware*
