Hi Ed... I looked, but for some reason, Mike's message has disappeared from 
my PINE mail directory... I'm posting this to the IML as well, so others 
may be able to benefit, comment, or make suggestions.

Basically, assuming we have a light moving from left to right, passing behind
a column in the center that is 10 units wide, you would do this (pardon any
glitches as I am working from my memory (bad enough!) on a Macintosh (even
WORSE), so I have no way of testing it):
	Create two paths... One that leads from the start point to -5 
		units (the LEFTmost side of the column) (we'll call it
		PATH1), the second that leads from 5 units to the end
		point (called PATH2).
	Move light #1 along PATH1 and kill it at the end of PATH1.
	Compute the number of frames it would be behind the column, add that
		number to the frame counter (you know what I mean?)
	At the proper frame, activate light #2 and move it along PATH2 to 
		the end.

This is a little more outlined than Mike's was... His was basically a
suggestion. This was my first effort at systemizing it, so beware of bad
logic on my part. As I said before, I haven't tried this yet to see how it
works (job, girlfriend, househunting, sleep, etc, etc), so if you do, please
send me the project to try out on my end.

Also, what is the filename in PINE that allows me to keep all mail... You 
know, the 'saved-messages' is for messages I want to (S)ave, 
'postponed-messages' for postponed messages, etc... Seems like when I 
started PINE the first time, there was a file for received messages or 
something.

As to my name, I go by either Drew or Andrew interchangably... Whatever 
you're comfortable with.
