AltOS 96
An operating system from an alternate 1996, with working apps.
The brief
Build a fictional desktop operating system from an alternate 1996. Invent its name, logo, boot sequence and visual language; do not imitate Windows or Mac OS. It needs a real window manager (drag, resize, minimize, maximize, focus and stacking order), a launcher or start menu, and at least five working apps: a paint program, a minesweeper-like game, a text editor that saves to localStorage, a web browser with three fictional websites inside it, and one surprise app of your choice. Synthesize the UI sounds with Web Audio.
