Tkinter Splash Screen (Python recipe) by Stephen Chappell
ActiveState Code (http://code.activestate.com/recipes/576936/)

This program is recipe 534124 re-envisioned. The code is mostly the same but was written with a slightly different style. It has also been tested on Python 3.1.1 and appears to work well with GIF images. Usage is the same as can be found in the original recipe. Any further improvements are welcome, and all are encouraged to use as needed.
