How it was made:

1. Claude can't browse X, so I had @grok analyze my profile and pick my 3 best posts

2. Gave @claudeai that analysis, my PFP, banner, and screenshots, and asked for a black and green theme

3. It wrote a Python renderer from scratch: vector graphics, 3D cards, and synthesized sound, all in code

It even vectorized my PFP and rebuilt the swirl background in green.
There's also a hidden message in the first 2 seconds which I didn't prompt. 👀
