The JavaScript code

var brd = JXG.JSXGraph.initBoard('jxgbox',{boundingbox:[-1.5,1.5,1.5,-1.5], keepaspectratio:true, axis:true});
var p = brd.create('point',[0,1],{face:'o', size:5, strokeColor:'red', fillOpacity:0.3, strokeOpacity: 0.3});
brd.create('arrow',[[0,0],p],{strokeWidth:5, strokeOpacity:0.7, strokeColor:'blue'});

var i = -1;
setInterval(function(){p.moveTo([Math.sin(i*Math.PI*2/12),Math.cos(i*Math.PI*2/12)],800); i++; },1000);
