updated PentTree

After the starfish design, I revisited the PentTree. The first thing I noticed was that it didn't make all the nice loops--connected rings of polygons. So I fixed that: check above the base, you should see eight pentagons that fit together making a loop.  Then I tweaked the pattern so it was a little better balanced. For the geeks, here's the code:

splitL{
   right
   scale 0.71925
   right
   ifsmall 0.002 { } {
   sides 5
   ifon none {
      paint green
      left
      create splitL
      right
      create splitR
   } { }
   }
}
splitR{
   scale 0.71925
   ifsmall 0.002 {} {
   sides 5
   ifon none {
      paint olive
      create splitR
      left
      create splitL
   } { }
  }
}

StarFish

This is a fun image that has a lot of pentagons and isosceles triangles. This pattern has neighbouring pentagons having the ratio of the .618 (the golden ratio). I'll do some more exploring to see if I can find another interesting pattern.
I think this may overly complicate the pattern but here is another.  Maybe this is more like an amoeba. It was a little tricky to make that inner spiral fit but it does.
