You can dowonload the Chameleons package
here. Whitin the zipped file you will find a description of the
application (sorry, in Italian); if you want to run directly the application go to the SmartChameleons/guiChameleons folder contained in the zipped file and click on StartChameleons.py (you have to install Python language on your pc).
The use of the windows generated by the program is quite intuitive.
Chameleons application comes from an idea of Marco Lamieri.
