Sounds like a great idea. The only thing I can think is to somehow cache
the timeframes to make it faster, and some sort of cool timeline widget
to slide with handles to make time windows and bar graph amount of data
per time.

As for animation, and animated gif of 12 frames would be easy, other
methods start to get very complicated, especially when talking cross
platform. Check to see if qt has anything. I'll poke around to see what
might be plausible.
