Vala helps you to use full power of GLib's object type system and libraries built on it without knowing and coding voodoo details of pure C OOP. Approach taken by vala is quite different from making bindings to different languages - vala code is translated to C and only then compiled, so Vala libraries can be pushed back to GLib ecosystem. One can even write a gstreamer plugin or linux kernel module(why not?) - that is very hard thing to achieve using other high level languages, even C++.
using this driver one can feed skype or other v4l2 program with webcam video with fancy video effects applied, or transmit video film, or even screencast.
also with this driver you can use webcam with several program simultaniously since loopback supports nonblocking reads.
all you need to try effects - is to install v4l2loopback driver and small helper program v4lsink to feed loopback with data and 2.6.28 kernel.
surprise your window-user friend - show him or her your contoured face and tell that this is a new computer virus.
