How can I add an effect to cheese that I created in python

[Rick T <ratulloch gmail com>]

Greetings All

I would like to add an effect to cheese for linux are there any examples of how to do this?

An example would be to place a running date time stamp at the bottom of the screen of the cheese video window

here's an example of the python code.  Keep in mind it wouldn't have the buttons of course but it will give you an idea of
what I want to have at the bottom of the cheese window.
