Stamen is a design/technology company known for its data visualization and open work (e.g. Stamen Watercolor). SteveG consults for Stamen now and then on mobile and is known for another open source map toolkit (WhirlyGlobe-Maply) which made the transition to Metal years ago.
We're floating a proposal with some of Stamen's clients to upgrade MapLibre Native to:
