GEGL extension for ruby and presentation app

I made a presentation about GEGL[1], the image processing and
compositing engine
developed to replace the aging core of GIMP at FOSDEM[2] this year. A
video of the presentation exists[3] but for the subscribers of this
mailing list I guess the sources and data files for the presentation
itself[3] is more interesting. The tarball contains the image files
used for the presentation, a cairo based canvas as well as the
presentation/authoring environment which is a ruby/GTK+/cairo/GEGL
