Billy developed the micro-site for A Warp Happening at the Barbican Centre, London. The event was a celebration of Warp Records' past three decades representing a roster of talent, including Aphex Twin, Flying Lotus, Yves Tumor, Squid, Evian Christ, Clarissa Conneley, among others.

The site featured four live streams of the event that displayed live performances, CCTV footage, and ambient recordings from the Barbican Centre. Alongside this, the site displayed event information, set times, and other technical details.

The development involved making a Node.js server to secure playback of the Mux live streams. Alongside this, the frontend was developed as a plain Vite application, using HTML, SASS and JavaScript.

The website visual design was led by Felix Luke, with design direction for the event led by Elliot Elder.
