Twenty pieces of a retro desktop: Desktop, DesktopIcon, Taskbar, StartMenu, AppWindow, Calculator, Notepad, Minesweeper, ControlPanel, TrayIcons, ShutdownScreen, BootScreen, Screensaver, Snake, Dock, RunDialog, DiskDefrag, WallpaperPicker, ClipboardPanel and LockScreen. The calculator really adds up and calls division by zero GAME OVER; Minesweeper and Snake are playable, first click always safe; START cascades its submenus without moving the rows already open; windows drag by whole dots; the screensaver's logo changes color at each wall and sparkles in a corner; the defragmenter is oddly soothing. Clocks that step back hold at zero, and typed or copied text never reaches the log. icon.Bomb is the new 12x12 mine.
