Just a funny little suggestion that takes advantage of the orientation sensor. My wife and I take turns doing dishes but always seem to forget who did them last. It's an expensive solution, but I could easily see the Twine being sandwiched between two plates, one with my name on top... one with my wife's name on bottom. When I do the dishes, I flip the Twine so her name is visible and a text message is sent to her "Your Turn!" -- when she does the dishes, she flips the Twine so my name is visible and I get the text message. Again, a pricey solution but definitely a good example of how the Twine orientation sensor could be used for tracking purposes.
If I've missed what you were originally saying, my bad If I need to post a picture of what I'm saying as far as axis of rotations and such, let me know and I'll hack one together. I'm working off my usual machine due to the holiday so I don't have all my tools handy!
