Hex 7 & 8

Jigsaw puzzle made from an L-System drawing from the system:
PREMISE : YXF
Rule 1: X=X+FY
Rule 2: Y=X-FF
Angle: 60°
Now, depending on how your Lsystem program evaluates these rules you may or may not end up with the same drawing. But I have confidence in the programmers over at sidefx.com (the make the movie special effects program Houdini that's been instrumental in creating fx for a bajillion movies)
