I just ordered around 240 odd of these things from EM4 Miniatures . The idea is to use them under the clear base of my flight stands for Bag the Hun and they, at 22mm, should fit nicely under the base of my 28mm minis for Nuts! and Six Gun Sound. The concept is to use colours to mark flights/schwarms in Bag the Hun and for Nuts!/Six Gun Sound the colours will represent the reputation value of the miniature (eg none for rep 3, White for 4, Red for 5 and Yellow for 6).
I also ordered 40 7mm six sided dice to use as altitude markers in Bag the Hun. Should stop them getting mixed up with the hand fulls of combat dice getting thrown around. At that size they could possibly stuck on the base with be blutac.
It's all great in theory... more info and photos after they arrive, which fingers crossed, if before
