This code is based on the original concept by Fayez Zaheer. It has been rewritten to handle the transitions differently, expand the script's flexibility, and fix a couple minor bugs in the original script. Fayez has found and fixed those bugs, but has not had a chance to release the fixed version (at least as of the time of this writing).

Special thanks to Fayez for helping to find a couple bugs in my own scripting :-)
