I'VE LAUNCHED MY FIRST FRIGHT-3! :) i'm curious about your launch technique  Arno  :)

it's revealed!   
i'm also curious to see your way  shredder ! :-)  
  
by the way, i'm struggling to find a clean launch method for fright-4, with 4 separate ff as starting point...

thanks! hmm our ways are totally different! :D my run is visible too :)  
  
i'll do some attempts in the editor with 4 flies, but have no much time at this moment :)

thanks! great! in the basics similar, starting with a vortex, but we both connect the 3rd firefly at a different angle. :-)  
  
recently i have found that almost all dancing formations with 3 or more flies are based around a vortex.  
there is one exception and that is  nesdori 's 5 bf moving up-right in 7 phases. that one does not contain a vortex! :-O

small update:  
  
i'm now sure that crawling b5-7 does not have a mirror version with fireflies!  
  
i found a necessary condition when a "mirrored" pair exists.  
  
the pair F&F and B&B satisfies this condition. so does the crawling-f4 and crawling-b4 pair. but crawling b5-7 not... :-)

 Arno  i think i found a way of launching fright-4. i do a few tries on editor and i have the clean automatic launch, which easily can be transformed to the manual launch of separated 4 fflies.

hi sherrder,  
  
indeed, yesterday i found a method as well.  
  
basically, i start with a vortex and combine your method and mine for the fright-3 (this cave) by connecting 2 ff at different places, one at left/bottom (like you did) and one at bottom/right (like i did).  
  
this works, although i was actually seeking a way to "upgrade" a fright-3 to fright-4 by connecting a forth fly while the formation is moving. and next "upgrade" the formation to fright-5 by connecting another fly. such method still seems impossible to me.

oh, now i see your pm. your method is similar to what i describe below, isn't it? :-)

# .font: font.text_2

# .font: font.text_1
yes indeed :) now i'm doing some tries with upgrading the moving formation. for now i've got a fright-4 which change to crawling-4 by spinning ff.

also fright-4 to sinking f5... very cool :)

there is many interesting behaviors. i have few cases saved.  
now i found a cool effect - fright 4 passes through multiple ff vortexes without interruption.

yes :) but with adding/removing free fflies :)
