From Granular Linux Documentation
Project Looking Glass is based on Java technology and explores bringing a richer user experience to the desktop and applications via 3D windowing and visualization capabilities. It supports running unmodified existing applications in a 3D space, as well as APIs for 3D window manager and application development. At the moment, existing application integration is supported for Linux and Solaris x86 platforms. The platform for 3D application development is available for Linux, Solaris and Windows platforms.
Looking Glass is often abbreviated as LG3D.
