Lines Pattern in grasshopper

Hi there, im trying to make this kind of random pattern in grasshopper but i’ve no idea how to achieve it.

Any ideas?

I see maybe four vertical bars coming up from each step. They are positioned either on the inside out the outside of the stair. That means you have eight possible positions on each step. Randomly select half of them. Count have many are insiders vs outsiders. Then i imagine two parallel lines on the hand rail. Divided them more or less randomly in the right number of points. Connect them in pairs.
Hope that helps. And do tell if you see some other pattern than I did.
