One of my friends from many years ago was an avid role-playing gamer. While I prefered pencil and paper games, he was into card, board and figure games. In the latter, he used the little plastic doodahs to support figures that were flying. Neato.

(For the hard of visualising, ground-based figures could occupy the same space as a flying figure without confusion. I'm not sure if the plastic got in the way of air attacks...)
