I have experienced Kim Jackson's media/visual art first hand and would
highly encourage all who are looking to have this component in worship.
Her website -
http://www.jacksonvisualmedia.com/
Gives examples of her work and experience.
Open for discussion: what are your opinions on utilizing visual aid in
concert with choral music? I've actually seen a Messiah performed with
media showing text and pictures. Does this augment the experience or
take away from?
