Compound transforms to create seashell form

Hi, can anyone tell me as a newbie how to do the following:

Transform a profile curve by a series of simultaneous move, rotate and scale transforms (then loft the resulting curve series to create a form similar to a seashell or snail shell). So curve #1 is drawn in Rhino or created in Grasshopper; curves #2 to N are each moved, rotated and scaled a little compared to their predecessors.

thanks

Lincoln

Hello
Did you use the search engine of the site or goggle with some or your keyword like seashell snail ?

Yes, and no I didn't find a helpful answer. I just want to find out how to simply apply more than one transform type at each step in a series of adjustments to an input curve.

So you are not happy with that ?

Yes that's very elegant; however it's too complicated for me to grasp and extract the simple principles I need to understand. I get how to make a series of curves with one transformation at each step; I don't know how to combine multiple transforms at each step such as rotate+move+scale. My attempts have not worked as desired. I have not been able to combine the transforms.
