A product launch video made entirely of code

Claude Code on Opus 5.5, one prompt, about eight hours: a launch video for a fake calendar app. Name, logo, UI, animation, soundtrack and sound effects — all code, and open source.

A launch video for a product that does not exist. Leon Lin asked Claude Code, running Opus 5.5, for a launch video for a fake calendar app — and it invented the name, the logo and the UI, then animated them, scored them and added sound effects. Everything you see and hear is code. One prompt, about eight hours of work.

The word "fake" is doing honest work. There is no company behind this calendar. The video is the artifact, and it speaks the full grammar of a real launch: the logo reveal, the UI walkthrough, the music telling you when to be impressed. That grammar used to come from an agency.

And it is open source, with the repo linked in the replies — so the "all code" claim is one you can read for yourself.

The work happened while he slept.

One prompt to Opus 5.5: he spoke to his computer for five minutes, Claude worked for twelve hours, and he woke up to a finished animated short.
