I wrote a humorous little play about the magi once. It was far too smart-ass for its context- it was performed in place of a sermon at some Christmastide service or other- and deservedly fell flat on its face. Even the guy who played Herod (the juciest part) told me afterwards that he'd have preferred something "more traditional".
Andrew Graham Dixon had a programme about the Medici the other day. Cosimo, founder of the dynasty, had a particular devotion to the magi- probably because, as Graham Dixon pointed out, they're the only rich dudes who emerge from the New Testament with any credit. He had the painter Gozzoli represent them in a couple of murals- one, in the chaste style of Fra Angelico, in the monastery cell where he (Cosimo) used to go on retreat- and the second in the Medici palace- which is thoroughly blingtastic.
