Combine first 3 ingredients in a pitcher; chill. Fill 4 glasses with ice cubes; add 3/4 cup orange juice mixture. Slowly pour 1 tablespoon liqueur down inside of each glass (do not stir before serving). Sprinkle with nutmeg.
Fun drink. I made this a few years ago for a 4th of July party. Simple to prepare with a neat twist, it's too bad there isn't a picture. The drink is orange with the blue liqueur streaming down the inside of the glass. I would definitely make again. I also didn't use the nutmeg.
