Tkinter drawing GUI is simple and clear, make some simple GUI enough, currently encountered a problem is not to display multiple pictures at the same time (not found at the same time to display the solution),
Back to the second, change to add an Update button, each time the button to update the image automatically, the comment out of the original kernel package, replaced by their own program can be
