Firefox is producing this warning on the `window.addEventListener('deviceorientation', onDeviceOrientation);` line:

> Use of the orientation sensor is deprecated.

No further information. I see no mention of deprecation at https://developer.mozilla.org/en-US/docs/Web/API/Window/devi..., so I’m not sure of the true state of affairs. It could have been accidentally tagged along with other functionality that is deprecated.

I believe the desire is for people to use the Sensor API instead now:

hmmmm firefox is missing this API as well

The "Gyro-Cube" example seems to have the alpha and gamma angles swapped.

I've written a simple move the ball to a hole game, with simple physics, using this features. One thing I had to take in account is when you flip your phone, the values are inverted.

Very useful as a pre-baked React hook, thanks!
