Chirp Pong

Simon Willison released Chirp Pong, a two-player pong-style game that runs as static HTML on two separate phones and transmits game state through audio chirps picked up by the web microphone API. Willison built the experiment with Claude Opus 5.5 Extra in Claude Code, and reported that the microphone-based networking approach appears to work.

Tool: Chirp Pong Another game experiment - I wanted to see if it was feasible to have a two player game on two separate phones running in static HTML where the networking code uses chirps sent via the microphone. It seems to work!

Build a two player competitive pong like game where two players use their phones close to each other and the game state is sent via audio noises which the web microphone API can interpret - but add graphical and gameplay twists to make it a lot more fun and intertwine than pong
