I think that was one by the Benedictine who does weird and often creepy icons of people who aren't Saints or even Christians. I think the one you're thinking of was Harvey Milk, who was Jewish.
Jason is correct. I'm virtually certain that this
is the one about which you ask. Robert Lentz, who painted it, is not a Benedictine, however. He is a Franciscan who, oddly enough, studied iconography at Holy Transfiguration in Brookline, MA (he apparently missed the classes on appropraiteness of subject matter).
The original of this and a variety of other 'odd' icons is to be found in Grace (Episcopal) Cathedral in San Francisco, I believe (the link is to the Cathedral's store).
