It is best used on a separate touchscreen laptop or +phone, to maximise your finger-dancing vibes. + +A great deal of effort has gone into making the LEDs look realistic, mainly +regarding colours saturating to white. + +It uses PixiJS for rendering, and a standard WebSocket for comms. + +## Setup +When you open the .html (no webserver needed), you'll see the default light +pattern: +![default pad state](img/default.png) + +Setup spicetools to expose the API on a specific port. I used port 9001 (which +will expose the "real" API on 9001, and the websocket API on 9002). This can be done via the commandline with the `-api 9001` flag, or via spicecfg.exe: +![spicecfg](img/spicecfg.png) + +Run the game, and the virtual pad should turn black as the connection is +established. From here, it should "just work". Click or touch the virtual pad to +send inputs to the game. + +## Known bugs +Sometimes feet get stuck, which is much more common on devices with limited CPU +(such as phones). I never really investigated good ways to fix this.
