I sketched this up one night, tracing some of Shaw's work, and basing it off of what he called the 'conjectural hanging edge structure' - perhaps the undercut we saw on the show/the model was supposed to be a hanging edge, not a huge cutting into?
I've thought about this very idea over the years. It would make sense, not cutting all of that "undercut" space out.
Interesting work. I look forward to keeping an eye on this.
