As promised on youtube: here it’s the source

( thx to saqoosha for the help on the flarToolkit issue of translating the flag fixed vertex… you can find his example of doing this on his site, but he maded it for away3d =) )

the code is very extended, so if you have any doubts post them here, we will try and answer all of them :)
