I just tried it on the Leap Motion blog with the same effect.
UPDATE: Ditto on my personal site, which has 3.9.1 (disabled all plugins for the sake of simplicity). As well, the two sites are on completely different hosting servers.
Really nice work on the plugin though; I dig the intro screen! Some thoughts:
(1) I feel like the motion scaling could be increased (so smaller hand movements result in bigger changes on the screen). Right now it's roughly 1:1.
(2) It would benefit from some additional UI elements, so that it's clearer what the hand is doing or about to do, especially for actions that are difficult to reverse:
- Scrolling works great and can be easily reversed, no problem there.
- Grabbing is a nice touch. Maybe I'm thick, but I don't see a loading bar?
- Swiping could have a green circle with an arrow (or some such) start to appear at the edge of the page where you're swiping. The full swipe would draw it out completely and trigger the action.
- Maybe make the hand icon on the lower right mouse-clickable to show the tutorial window?
