reb Class REB_TrapShapeFibonacci

Object common:Generic common:TrapShape reb:REB_TrapShapeFibonacci

class
TrapShape:REB_TrapShapeFibonacci

This shape based upon Fibonacci numbers

The trap shape is determined by distances from Fibonacci numbers. One of the interesting characteristics of the shape are multiple 3D like arrows that follow the flow shape of the trap.
