Not the Zipper

Well this is the pattern that is related to yesterday's zipper. The program to create this pattern is fairly simple. It has two different local patterns: one that looks like a propeller spinning clockwise and one that looks like a propeller spinning counter-clockwise. In the program below I have labeled them zig and zag.

zig {
  sides 5
  paint blue
  sides 3
  ifon none {
     paint orange
     create zag
     left
     create zag
  } { }
}
zag {
  sides 5
  paint blue
  left
  sides 3
  ifon none {
     paint orange
     create zig
     left
     create zig
  } { }
}
