Amiga clock

A little desktop of clocks, all live: an analog Workbench-style face, a big block-glyph digital readout with a blinking colon, the bouncing Amiga boing ball with the time overlaid, and a fourth window that nests all three in a draggable split grid. Every window moves, resizes, zooms, and closes like any other — the standard windowing shell, running unchanged in the browser.

A single ~12 fps timer drives two signals — a frame counter for the spin and bounce, and the current time — and the reactive views bound to them repaint themselves; nothing redraws by hand. Drag a title bar to move a window, drag a corner to resize, F2 to zoom, F4 / F5 to tile / cascade, F6 for the next window, and Tab to cycle focus.

A desktop of live clocks — analog, digital, and the bouncing Amiga boing ball — each in its own window.
