title: How can I save an animation created with tkinter's gui and canvas?
body: <p>I have a working animation, but I'm wondering how to save the animation after it displays once.</p>
  <pre><code>gui = Tk()
  canvas = Canvas(gui, width=800,height=600,bg='white')
  (objects/shapes created here)
  for i in range(num_frames):
       canvas.move(blah blah)
       gui.update()
       time.sleep(.01)
  
  gui.mainloop()
  </code></pre>
