Gravilux 1.2 is now available in the app store. It features a massive speedup–up to a hundred times faster–even on old iPhone 3s. Try Gravilux with the maximum number of stars to get a true taste of the improvement. Also new is antialiased points: try very low gravity and notice how the points actually move at a finer resolution than the pixels on your display, moving between pixels. And several other interface refinements are featured in this version. See below for a gallery of color images from Gravilux 1.2.
