Tried it -- it doesn&#x27;t work on my Linux laptop touch-screen, because hand gestures count only as mouse moves, not drags. Windows might differ.<p>Update -- it does work on an Android tablet, where hand gestures do count as drags. Very nice -- if only my tablet were twice as big so my fingers wouldn&#x27;t get in each others&#x27; way.<p>Pretty slick. Now to get it as an open-source app.
