Used Opus 5.5 and GPT Astra 6 to vibe code a music visualizer over a few days. It's essentially audiosurf in your browser - you drive to the song and the world dances to it. This was kind of a sentimental one, since a music visualizer was one of the first web dev projects I built and deployed. Back then, you uploaded an MP3 and it would play and visualize it. No idea how I put it together circa 2014. These days you paste a YouTube link (who still has MP3s??), and the visualization is built in Three.js instead of my old jQuery setup.
