The Arch: Using Rust & WebAssembly to animate 30k colored LED lights

In June, Mozilla collaborated with artist Ian Brill to create an installation called the “Arch” at JSConf EU in Berlin. This interactive environment allowed people to experience the intersection of art and technology in a physical, pulsating, immersive way. The environment also created an opportunity for JavaScripters and friends to create animations and experience the underlying capabilities of WebAssembly and Rust.
