Had Claude Code make a 90s promo for my app. Every frame and every sound is code

No After Effects, no stock music. Claude Code (Opus 5.5) wrote the whole thing in Remotion (React), and even the soundtrack is synthesized in plain JS: a techno track plus 176 sound effects, all timed off the same timeline as the animation, so everything lands on the beat. Bonus: the same code renders this 4K video *and* runs live on a webpage as a \~340 KB embed instead of a 30 MB file. My job was basically creative director. I went back and forth with it a few times ("these transitions look like 90s PowerPoint", "that blur looks like a bug", "the music feels too old"). How it started: "Can you create me a 1:30 min professional video for Compress. I've a good design taste so don't come up with weak shit. Stay in brand but sky is the ceiling for your creativity…" It's for my own product, so no link. Happy to answer questions about how it's set up.
