Creating an animated graphics overlay with Python

I'd like to hear the best means for displaying graphics that move on-screen as an overlay with Python. The intended initial platform is Linux. I've 开发者_运维技巧worked up some small demos using PyQt using frameless windows and looping and updating their location on screen. This works, but I have a feeling it is not the ideal solution.

The end result is an activity indicator that would show more objects swarming in an upward direction as activity increased. That would result in spawning perhaps a hundred windows in a go and that is why I think my PyQt demo is not optimal.

I'm open to any suggestions since this will be an open project and installing obscure modules is a non-issue.

There are examples for making transparent / unclickable windows in java and in javascript. Here are a couple of transparency related posts for QT.
