Vision: Cyrus will empower you to easily build, mash up, animate and program your own corner of an open, global, online, shared 3D virtual world and augmented reality. A world that is all linked up, just like the Web. You will be able to create objects within the live online world, then animate them on the spot with simple rules. Cyrus is an open Java server and Android app. And Minecraft Mod, obviously.
