Do you think Da Vinci sat at his table and thought "let's invent the helicopter" (with a nice unique memorable name for his work in progress)?

I would rather imagine Da Vinci being supposed to draw some boring architectural work or even writing against his will to his great-grant aunt. And then a paper fell off his table, spinning away. And then I imagine Da Vinci drawing a spinning paper on the margins, and adding equations, schemas, and getting deeply inside this new project, which becomes clearer in his mind as he works on it, without ever having a name.

This is exactly why I hate deciding a branch name before some tasks and I love `git add -p` which allow me to add a bucnh of unrelated things in the work tree and extract the juice later.
