Rust

“Three or four times only in my youth did I glimpse the Joyous Isles, before they were lost to fogs, depressions, cold fronts, ill winds, and contrary tides... I mistook them for adulthood. Assuming they were a fixed feature in my life's voyage, I neglected to record their latitude, their longitude, their approach. Young ruddy fool. What wouldn't I give now for a never-changing map of the ever-constant ineffable? To possess, as it were, an atlas of clouds.”
― David Mitchell, Cloud Atlas
