I have been known to make a few shadow gestures myself.......but enough about that! This is great fun to do, providing you are double jointed in some cases.......... But Wait it does not cost you $19.99. Think of the fun you could also have being the life, and, or the entertainment at your next gathering. What a way to surround yourself with a crowd...before you know it you might be signing autographs. I became invisible once at a party, and played a whole game of tennis in a living room full of people, without them knowing, seriously,...(oh those parties from the past)......this is much easier to do than that. Could also be a workout, or warm up for those hands on a chilly morning before working in the studio. Let your hands be your guide. Artistic people it's always about the hands!
