Mozart wrote a piece of music that can be played upside down!  And it's a nice piece!  It can be performed as a duet or trio on two or three piano/keyboards.  Second performer plays the same page as the first performer only UPSIDE DOWN. The third performer can choose a string sound on their keyboard.  The second page has chord symbols for either duet partner to play or a third piano player to accompany.  Lot's of FUN and you don't have to wait until April :-)
