"Pie Nav"

Design as part of my day job as Head of Design Mobility at Cloud Sherpas, the "Pie Nav" is an extendable, configurable navigation tool intended to be usable across multiple apps. I handled the design as well as the development for iOS, it is currently used in one of our apps: https://itunes.apple.com/us/app/docbox/id540650159?mt=8

I'd love to be able to show the animation but I haven't got a decent screen recorder set up.

Interesting note: the "pie slices" are all drawn dynamically so the code can handle any amount of slices from two up. Although in practice the design works best with six or less.
