After some hesitation I decided
to publish this picture.
Maybe it´s not pretty but interesting
for several reasons:
1.I´ve never seen or used the shape - Double
  Mandel with 2 additional instances.
2.The interior for me definetly looks like
  a Paul Klee picture. Remember I said I could
  imagine to convert one of his works?
3.It is a mandel type with 3(!) separate inside
  channels that dont collide. Every formula works
  differently if used as Mandel inside. Of course
  it´s not the simple lake it seems, but the
  structure remains invisible if no inside is
  specified.
4.The outside - ManyMods - can be forced to
  stay inside using the border values. 
5.As I was determined to get what I imagined
  many hours of fine tuning were necessary.
Maybe you like it too.
