SwiftUI Metal shader
Earth
A dotted globe spun from a real land mask, with three styles — Metal Dots (lit chrome globe), Radar Ping (green sonar sweep with land blips), and Contour Mono (B&W elevation contours). Pure colorEffect, no source image.

How it works
Earth is a real [[stitchable]] Metal shader, not a video or an image. It runs as a SwiftUI .colorEffect, so it paints any view you attach it to. You shape it with sliders in a live preview, then export the .metal file and the SwiftUI code that uses it, or the Web version. No MSL to write.
