What are some float ideas for Michael Jackson's song Black or White?

My son’s school chooses a theme each year for their football homecoming activities. This year, they have chosen Michael Jackson, and each class chose a different song of his to represent. My son’s class has “Black or White”, and they must dress according to their song on a certain day for homecoming week, as well as decorate a float for the parade and wall in the school. Any ideas as to how you would decorate the float/wall and how you would dress?
