As I indicated he might, Barry has now done a post explaining what Luke Murphy actually does to create his computer art and enthusing about its wonderful painterly animation.

A lot of artists are working with technology and art, but I don't think that many of them pull off using the strengths of technology, such as writing a program which then generates the art (possibly in random ways like a high-tech bow to John Cage), rather than just using it as a useful animation or painting tool. I think Luke Murphy does pull off that feat. The works are engaging and beautiful, plus there is an intelligence to them that one can appreciate.
