Olin,

That's perfect! I just happen to have a camcorder with me (which is really
my parents' and would normally be with them) for reasons that have nothing
to do with this project! I'm charging up the battery now and I'm going to
try your idea. This is definitely one of those "why didn't I think of
that?" occasions.

Thanks,

Sean
