Show HN: I was curious about spherical helix, ended up making this visualization (visualrambling.space)

The motivation came from constantly struggling with overcomplicated invoicing software while working on side projects. I wanted something minimal, scriptable, and developer-friendly.

Repo: https://github.com/username/invoice-cli Docs: https://github.com/username/invoice-cli#readme

I’d love your feedback - Does this solve a real pain point for freelancers/developers? - What features would you expect in a minimal invoicing CLI? - Any ideas for integrations (e.g. Stripe, Notion, etc.)?

Thanks for checking it out!
