well i thought of something like realtime video controlled fluid emitters
for an installation (bodymovements distorting virtual atmosphere (like hot
steam)). i thought of realising this with particles but allways got somehow
"to rough" grains.

i thought that to.... it was just a question of "somehow and maybe"

yes i think they could be quiet handy-- thanks
