pyChing is a program that allows you to 'consult' the I Ching. The I Ching is an ancient Chinese book of wisdom, which, apart from being read as a book, has also traditionally been consulted as an oracle. pyChing allows you to perform an I Ching 'reading' using the coin oracle, and then look up a brief interpretation from the I Ching. pyChing is completely written in Python, a cross platform, object oriented, programming language, using the Tkinter interface to the Tk GUI toolkit.
