We're currently working on the upcoming Genode 8.11 release, which will include the device-driver environment and an ANSI C library. The release is scheduled for mid-November.
In the meantime, you may have a shot at our compiled Live-CD image showing off the current state of the Genode OS Framework. The Live CD features a fully graphical demonstration that presents the fundamental concepts of the Genode architecture in an interactive fashion. It runs directly on PC hardware and has been tested on Qemu and VirtualBox.
