oh wow! looks really cool.   
i think i see the method, however at first sight, the distance between both fireflies in the centre part surprises me. i would expect them to walk closer for a double/connected explosion... :-)

thanks  Arno  :) hmm, the distance between this two fireflies is set to double blast :) in my intended way it works :)
