When I think about SO? architecture's works and approaches, what comes to mind is simplicity and modularity. I wanted to provide the references of sheets and drawings that refer to architecture with lines. The idea of drawing letters "S, O and ?" with rotating a single line revealed the general language of the poster.
Common geometric shapes based on the circle were formed by lines, creating the letters. At the same time, the lines evoke roof/house in abstract forms on a two-dimensional floor.
