[ LEAP MOTION + PYTHON ] Can anyone help me improve this python code so that it will run smoothly as expected? I am working on a project integrating a Leap Controller with a graphical user interface (GUI) using Python Tkinter. To get me started, I seek for an example code but then the sample code is kind of faulty since the tracking stops at certain frames. If you have the controller, please do try so that you can see what I am talking about here. MANY THANKS! :)
