I modified a JavaScript maze game to be controlled by SMS text messages a couple weeks ago. The SMS messages go to a stdlib + messagebird FaaS which updates a redis database, and then a NodeJS server script uses WebSockets to send data to the front-end maze game. Not super practical as an input to the game of course… I built it as a fun way to demo a bunch of different technologies working together to small groups of students interested in technology at an event. I don’t know why, but SMS as an interface brings back that “magic” feeling of technology to me.
