title: Is it possible to save in a file an animation created with Tkinter?
body: <p>I wanted to use Python to create animations (video) containing text and simple moving geometric objects (lines, rectangles, circles and so on).</p>
  
  <p>In the book titled "Python 2.6 Graphics Cookbook" I found examples using Tkinter library. First, it looked like what I need. I was able to create simple animation but then I realized that in the end I want to have a file containing my animation (in gif or mp4 format). However, what I have, is an application with GUI running on my computer and showing me my animation.</p>
  
  <p>Is there a simple way to save the animation that I see in my GUI in a file?</p>
