Volvelle Possibilities

Just a little doodle to set me thinking. Even limiting myself to concentric circles for the most part, I kept coming up with possibilities for using Volvelles. I started with the idea of surveying what could be done with a circle and a pivot. Information can be obscured, indicated, or illuminated with a Volvelle. The second circle below could be a changing face. I’m not sure how you illustrate or derive a function with such a thing. But, like I say, “just a little doodle.” Transparent colored circles could illustrate combinations and layered traces could illustrate circuits. The final Volvelle on the bottom right plays with the idea of a spiral around a pivot, that is a turntable. Is the needle on the top or the bottom? Is there a needle guide? Maybe musicians could use them to demonstrate a musical passage. Just run an amplifying stylus through the grooves and you have yourselves a tune.

VolvelleDrawingIf I may muse for a bit, volvelles are a fascinating way to arrange a table. A pivoting table? Wheels within wheels. If you stack two logarithmic number lines, you have a slide rule. Clocks are volvelles with arms instead of discs. There are not only volvelles for calculation, but volvelles for remembering state capitals and volvelles for learning grammar rules. 

So many departures on a thing which turns upon itself. You might even wind up with Willie, Freddie, and Flaco.

Come back, come back to your arms again. I’ll come back to where you are.
