of interest -> Fifa has a long tradition of releasing and naming a "special" football at every world cup.
Chris's 3D flags are wrapped around a "Telstar" fussball (released 1970 mexico world cup).
No doubt, this method could be used on the "Tango"(circa 1978 Argentina), the "Tricolore" (France), the "Teamgeist" (Germany), the "Fervernova"(Japan), the "Jabulani" (Sth Africa) and... the "Brazuca" !
wonders if I could wrap a flag over the pointed end of a rugby ball

cheers
