Hey Mario, 

This looks really interesting! Never thought of that, great idea. Can
you explain what the different symbols (+-|) etc. represent? I can't see
why I couldn't interpret this if I knew that information as all this
information is available to me at my finger tips!:) 

Anyway if you can tell me how it works I'll hopefully make some sense
out of it:)
