I think this is the best way to do it. Because of the way the scene 
files are structured, variables are always initialized. You can just 
check to see if the variable already exists if you want that one to be 
persistant.

I really don't have any ideas about this, I do kind of like it the way 
you did it, though.

This should definitely be kept, and just carefully documented. It could 
be very useful to be able to control the object blur motion with 
something in addition to the clock variable, using a variable 
incremented within the blur statement as a counter.
