Staircase

I was browsing Dezeen the other week and came across a really interesting staircase by Paul Cocksedge. I was particularly interested in the 3 diagrams showing how the staircase design evolved. I am unsure what software was used for the design process but I instantly thought that Grasshopper would have been a great tool to explore the potential design solutions and parameters. It resulted in me producing an algorithm displaying how it could possibly have been used.
