Javascript Custom Slider

This project is about creating a vertical slider? (in Javascipt)? which must have the following custumizations * It must be created in JavaScript * It must work on all (major-) browser (IE,FF,OP,SA) * Its length must be set in Centimeters (not pixels) (script init param) * It must be possible to set the number of tick-marks (script init param) * It must be possible to change the sliderhead (-imag) (script init param) * The scale must go from 0-100 * It must be possible to set the slider head to a certain position (Jscrip function) * It must be possible to retrieve the selected value that the slider head currently points to A first prototype was listed here <[login to view URL]>. Note that re-using this jscript implementation is useless as it has several quirks, but you sort of get what we are trying to accomplish.
