The underlying JavaScript code
var brd = JXG.JSXGraph.initBoard('box', {originX: 300, originY: 300, unitX: 1, unitY: 1});
var t1 = brd.createElement('turtle');
var t2 = brd.createElement('turtle');
t1.setPos(200,0);
t2.setPos(0,0);
var n = 64;
var delta = 360.0/n;
function chase() {
t1.fd(20);
t1.lt(delta);
t2.lookTo(t1.pos);
t2.fd(20);
action = setTimeout(chase,100);
}
chase();
