you'll have to write yer background process from another piece, 
but the part about allowing the user to rubberband an area of the 
screen *is* done in SNAPSHOT(6D).  source for this lives in
/usr/people/4Dgifts/iristools/imgtools/snapshot.c  
refer to the section about 4Dgifts in the "Release and Installation 
Notes" where it lists how to install IF you don't have a 
/usr/people/4Dgifts user account/subtree loaded on yer system.
