Grasshopper

algorithmic modeling for Rhino

logarithmic spiral

What is the most elegant (efficient, simple, clean) way to define a logarithmic spiral in xyz?  Attached is a gh I got from modelab intro tutorial #7: "spiraling".  Am new to grasshopper but not to 3D modeling-have been using Autocad for years. Have taken 20+ GH tutorials and am attempting to learn how to think parametrically.  I ask this question because this geometry is essential to everything I am doing now.  Any input or direction is greatly appreciated.  Old dog, new tricks.  Thanks,  David
