creating a surface comprised of multiple components

I have a script that allows two components (an open and a closed) to be placed on a surface. the control of this placement is based on an angle of curve and the normals of the panels of the surface. Ultimately Id like a surface that can react to sunlight but instead of it being a coded (either open or closed) I like to be able to place a variety of components with a gradient of opacity. For starters, I would like the script at the very least to be able to place (x) number of components on to the surface. The reaction to light (or the source curve) can be developed after.

I appreciate any help that can be offered. Admittedly I do not fully understand grasshopper but am excited at the potential it offers.

Attached is the script I have thus far.

Thank you
