Is there any way to pull the script off of the Arduino?
I forgot to save my work before shutting my computer down. :-[
I have no idea if it is possible to read what you wrote in RAM.
but what is on your arduino is not a "scipt" it's compiled code, you will not be able to retrieve your C code from that...
You've just learned the first lesson in programming - save often. 
If you managed to compile it, then (on Windows at least) it creates a temporary folder with all the files. It would be somewhere like this:
C:\Documents and Settings\<<user name>>\Local Settings\Temp\untitled2736.tmp\sketch_aug31c
So it might be worth looking in your temp folders to see if it's still there.

Good thought, Andrew. There would also be a folder named applet in your sketch folder. If it is still there, the [sketch-name].cpp file in that folder would have all your code (plus a little more) in it too.
