Framebuffer Manipulation with Vigra(numpy) Interface for Linux Framebuffer

I wrote an interface that allows accessing a Linux framebuffer using vigra(numpy). It is at a very early stage and lacks documentation and offers only very basic functionality (writing an array to the framebuffer) so far.
This video shows the library in action. Again, all that is included is vigranumpy and Linux framebuffer. No X or other graphics system is used.

Another video showing framebuffer manipulation in action (vigra.filters.gaussianGradientMagnitude), this time captured directly from framebuffer using ffmpeg.

As always, the code can be found on my git repository:
