garlicsim_wx is a wxPython-based GUI for garlicsim.
The final goal of this project is to become a fully-fledged application for working with simulations, friendly enough that it may be used by non-programmers.
garlicsim_wx is in a far less mature state than garlicsim. Also, it is not licensed as open source. (Though the source code is available and not obfuscated.) I have not yet decided if the gui will be developed as an open source project or as commercial software, so in the meantime it is officially closed source.
