If you have, there's an EASTER EGG (ooh!) go to special features, and select "D&D Beginnings." Then click left. The unicorn's horn will light up.
If you play the unicorn's horn (that's probably obscene innuendo in the early middle ages) you'll see in STARTLING THREE BIT COLOR a HIDEOUS cartoon of ME!!! Yay! I'm the easter egg!
Crown me lame :)
