Actually, I was kinda wondering.  Do you have to be dead for the
portraits to "come alive" rather than just flitting in and out?  I
mean, I know that pictures are animated, such as newspapers and
Colin's pictures, and even the trading cards.  But of the paintings,
do we really know of one of someone who is alive?
