It's not easy to create screenshots for a library project. However, Johan Lindberg, who also participates to the PyCLIPS development, has converted the examples provided with the CLIPSJNI interface using wxPython. This page shows some screenshots taken from these examples.
1. Screenshot from WineDemo.wx.py (Windows XP)
2. Screenshots from AutoDemo.wx.py (Ubuntu Linux)
3. Screenshots from SudokuDemo.wx.py (Ubuntu Linux)
The example applications used to take the screensots above can be downloaded here.
