array along curve using points and incremental rotate in a single axis..

Hello all!

Really new to grasshopper however not able to produce what I want in Rhino 4.  Our company is upgrading to Rhino 5 just waiting on delivery :)  However Grasshopper has me very intrigued and am trying to figure something out.

I have a curve like a stretched out s curve that i would like to array planes along but they all stay parallel to each other.  Would like to place them at points created at intersects so i have a constant verticla distance between them as the continue along the curve.  Thats easy to do with out grasshopper the real trouble is coming is i want them to do that but incrementally rotate along the z axis.  Its for a building concept and any help would be greatly appreciated!

Kindest Regards

Ryan
