Today I'm going to let you in on a secret. It's how to convert the position on a slider to a rotation. Well, actually its technical name is 'ratio conversion' as we don't touch on things like sine or cosine.
Above is the highly advanced Flashkitorinox (sic). What happens is you set the position of the slider-knob (which is a value between 0 and 164) and converts this to a number between 0 and 180. Really quite simple. High School simple actually. So, ok its not THAT much of a secret... :)
