Composition: Follow Leap Position Trail

Based in the DrawTailBehindMouse composition (in the manual, page 79), but instead of the mouse position, I used the hand position to draw the trail. The Grab command define the thickness (open hand show nothing, you must grab your hand a little: more grab, more thickness. Its a very simple composition, remixes are more than welcome :) I'm a very beginner, happy with the 2.0 version...
