Incredibly nice effect. But it is so unfortunately not very well working with FF, so for websites with significant part of FF users it is a no to use it. Person

Incredibly nice effect. But it is so unfortunately not very well working with FF, so for websites with significant part of FF users it is a no to use it. Personally I admire your effort. Imagine the interface where you should put the ball into the hole to achieve a menu item. Will work only on smart devices with gyroscope, however.
