"GGL resembles SuperKaramba, Screenlets, gDesklets, and KDE 4's Plasma. All produce similar results and offer similar gadgets, and the only reason to choose one over another is if it offers unique gadgets you're particularly interested in. Some programs are compatible with each other, allowing you to run gadgets from other programs; there's even talk that Plasma will be able to run GGL gadgets directly.
