jquery circluar slider?

[dev82]

Hallo Leute,

ich habe auf einer Testseite: Circular Slider Demo | revision30
einen Slider erstellt mit folgendem Code:

$(document).ready(function() {
/*Slider */
$('.slider-input').each(function() {
      var currVal = $(this).val();
      if(currVal < 0){
          currVal = 0;
      }
    $(this).parent().children('.slider-content').slider({
        'animate': true, 
        'min': -1, 
        'max': 201,
        'value' : 201,
        'orientation' : 'vertical',
        'stop': function(e, ui){
            //$(this).prev('.slider-input').val(ui.value); //Set actual input field val, done during slide instead

            //pop handle back to top if we went out of bounds at bottom
            /* 
            if ( ui.value == -1 ) {
                ui.value = 201;
                $(this).children('.ui-slider-handle').css('bottom','100%');
            }
            */
        },
        'slide': function(e, ui){
            var percentLeft;
            var submitValue;
            var Y = ui.value - 100; //Find center of Circle (We're using a max value and height of 200)
            var R = 100; //Circle's radius
            var skip = false;

            $(this).children('.ui-slider-handle').attr('href',' UI.val = ' + ui.value);

            //Show default/disabled/out of bounds state
            if ( ui.value > 0 && ui.value < 201 ) { //if in the valid slide rang
                $(this).children('.ui-slider-handle').addClass('is-active');
            }
            else {
                $(this).children('.ui-slider-handle').removeClass('is-active');
            }

            //Calculate slider's path on circle, put it there, by setting background-position
            if ( ui.value >= 0 && ui.value <= 200 ) { //if in valid range, these are one inside the min and max
                var X = Math.sqrt((R*R) - (Y*Y)); //X^2 + Y^2 = R^2. Find X.
                if ( X == 'NaN' ) {
                    percentLeft = 0;
                }
                else {
                    percentLeft = X;                    
                }
            }
            else if ( ui.value == -1 || ui.value == 201 ) {
                percentLeft = 0;
                skip = true;
            }
            else {
                percentLeft = 0;
            }

            //Move handle
            if ( percentLeft > 100 ) { percentLeft = 100; } 
            $(this).children('.ui-slider-handle').css('background-position',percentLeft +'% 100%'); //set css sprite

            //Figure out and set input value
            if ( skip == true ) {
                submitValue = 'keine Seite';
                $(this).children('.ui-slider-handle').css('background-position',percentLeft +'% 0%'); //reset css sprite                    
            }
            else {
                submitValue = Math.round(ui.value / 2); //Clamp input value to range 0 - 100
            }           
            $('#display-only input').val(submitValue); //display selected value, demo only
            $('#slider-display').text(submitValue); //display selected value, demo only
            $(this).prev('.slider-input').val(ui.value); //Set actual input field val. jQuery UI hid it for us, but it will be submitted.
        }
    });
});


});

wie kann ich den Slider nun so einstellen, das er sich direkt um 360grad dreht, natürlich sollte sich auch die Grafik drehen um die eigene Achse.

Danke für eure Hilfe.
