A tinker was originally an itinerant tinsmith, who mended household utensils.
 It is part of  an image that come to mind when  I work with Tkinter.

Tkinter is Python's de-facto standard GUI (Graphical User Interface) package.

 Thinking in Tkinter ... "I've been trying to teach myself Tkinter out of various books, and I'm finding it more difficult than I think it should be. ..." S. Ferg.
