I was recently inspired by Robert Rodriguez's interviews on Lex Fridman, Joe Rogan, and Tim Ferriss where he described his process of leveraging notecards to solve problems.

Originally a writing tool, he has applied it to various domains boasting that those cards have earned him $1 million.

This is also a test of pure "vibe coding" (Cursor Gemini 2.5 Pro - Thinking). In the repo, I've included the full conversation.

This is still not something I would do in production code. But for a greenfield project, it seems like an incredible prototyping tool.
