Revision 4. </p> <p>EDITED: A small animated graphics demo in Tkinter, displaying a 1990's style Rotozoom, more interesting than the TV snow I posted previously. The Tkinter management part is just the same. The code is a little longer as some trig tables must be precalculated for speed. The window size corresponds to the resolution of the old DOS screen 13, as I originally coded the demo for Qbasic. </p>

(I could just add code to randomly select 2 white cells and change their colors to something else but I thought it looks better this way.)</p>

Revision 2. </p> <p>The Python Imaging Library (PIL) makes many tasks easy in digital photography. This recipe shows how to make a "contact sheet" of images, a single image with thumbnails of many different pictures. It's limited in that it will only work with pictures of the same shape, but you can make some really fun images.</p>
