i thought it would make sense to make demo caves with all known dancing fly formations (dff) so everyone can easily rebuild them for an own cave :)  
  
these are all existing dff with 2-3 flies.

if you want to copy a dff, be aware that also the facing directions of the flies are important. you can see them when you clone this cave! :d
