hours, days spent developing, and testing, and swearwords because it doesn't work, and beers, and diagrams, and change again, because it won't work as you wish, and again, change it, modify there, test again, nothing, and rubber on your diagram, and change there and there, and finally, after other days, and nights, and beers, and coffees, and -yes- swearwords, you see it, and you are as happy as a child :) http://i.imgur.com/pN6j9z...
