GoKawiilDeveloper builds interactive Casio F-91W demo using XState statecharts
A developer created an online, interactive model of the Casio F-91W digital watch that implements its logic using the XState statecharts library, building on an earlier digital recreation by Alexis Philip. The project pairs the watch interface with the Stately visualizer so users can see states and transitions as they interact with the watch, referencing David Harel's 1987 statecharts paper which originally used a digital wristwatch as its example.
