I put together a halloween display using a Kinect and pygame for my front yard (very quickly hacked together by the way):

Pygame is nice and easy to use, though I think I'd go with something else next time, as it doesn't support multiple monitors or OpenGL very well. I see OpenGL stuff at the top of the Pygame 2.0 change list so maybe worth checking out.
