Please feel free to paste links on the talk page, saying whether it's a good or bad example - I will add prose and explanation. I'll also be gathering examples on Friday at the Zurich hackathon. I want to polish this and get it approved during the hackathon.
(I'm still cleaning up the detailed explanation of each principle.)
