Interesting/Cool Scaling Mechanism Designs

I love (but really hate) how this thread has derailed from the coolest climbing mechanisms to banter over one guy’s pedantic ridiculousness. If we really want to get into math and definitions from a dictionary in the name of legality, shouldn’t we start a new thread? There are 2 weeks of new mechanisms yet to debut and I’d love for them to have a home to chit-chat about.
