Slotronome
A slot machine that deals you a tempo.
Slotronome is a pixel-art metronome designed to break the habit of practicing only at a comfortable speed. Set a range, pull the lever, and it deals a new tempo—then keeps time with accents, changing meters, and optional automatic re-deals.
The oak cabinet, brass trim, amber reels, scanlines, glare, motion, and synthesized machine sounds are built from HTML, CSS, and Web Audio.
