I was sad to see pynche (“Punchie”) go!
It was a nice, simple demo of the capabilities of tkinter (IDLE is too hard for a beginner to have a go at understanding, so I used pynche as an example in my courses. My clients often don’t have any install rights, or internet is not available, so installing is not always possible.)
And it was actually a useful colour picker.
