Two items of interest:
There's a new Turner exhibit in Britain. Follow this link to a blog post about it: http://linesandcolors.com/2013/12/30/turner-the-sea/
In that post, there's a link to the museum. Once there, click on the arrow to see some animations of Turner's works (or buy your tickets if you will be in UK for the show!). Also, go down and click on the link for the book, which takes you to amazon and some images from the book, some of which are watercolors.
This link takes you to a short (3 min.) animated film of some of Van Gogh's paintings. Interesting possibilities! http://www.youtube.com/watch?v=MPQSN3fNLF4&feature=player_embedded
