+/* This is simply a proof-of-concept for using cairo to implement a
+ * design idea for an OLPC boot-time animation. The animation here is
+ * implemented to mimic an animation originally provided as a
+ * Quicktime movie by Rebecca Allen <rallen@arts.ucla.edu>.
+ *
+ * So far, this animation has been developed exclusively on an x86
+ * laptop with GTK+ targeting the X Window System. No guarantees are
+ * provided as to how this might perform on an OLPC XO machine. What's
+ * likely desired is to write the application to use cairo image
+ * surfaces, and augment cairo to support targeting the XO's 565 image
+ * format directly.
+ *
+ * And obviously, to serve as a real boot-time animation, code will
+ * have to be written to advance the animation according to various
+ * system events, instead of using the hard-coded timeline below.
