Don't know if you have ever seen the vampire series True Blood, but in the intro they appear to show a fox decomposing in fast speed...and i can't say it did anything for me!
That said sounds like an interesting project, where \ how are you going to do this? I assume you neighbours would not like be too keen on a rotting carcass for a few months!
I guess they point will be taking the picture from the exact same spot each time, unless you are planning on focusing Macro style on different bits.
Good luck, I'll probably peak from behind the sofa periodically!
