Works on iOS 7, 8, 9, and 10. Has arm64 support.

PineappleSpinnerLS adds a fully-functional page to your lock screen where you can tap a button to spin a pineapple, and tap another button to accelerate it (much to its dismay).

I wrote this in about 30 minutes for use as an example project for my release of the LockPages Public API + Example Projects (which can be found at the GitHub button above).
