Step3.

Add CSS Animation

@keyframes move {
	from {
		transform: rotate(0deg)
		           translate(200px)
               rotate(0deg);
	}
	to {
		transform: rotate(360deg)
		           translate(100px) 
               rotate(-360deg);
	}
}

Step4.

Add jQuery

jQuery(function($) {
    $(".bokeh1, .bokeh2, .bokeh3, .bokeh4, .bokeh5, .bokeh6, .bokeh7, .bokeh8, .bokeh9, .bokeh10, .bokeh11, .bokeh11, .bokeh12, .bokeh13, .bokeh14, .bokeh15, .bokeh16, .bokeh17, .bokeh18, .bokeh19, .bokeh20").mouseover(function() {
        var dWidth = $(document).width() - 50, 
            dHeight = $(document).height() - 50, 
            nextX = Math.floor(Math.random() * dWidth),
            nextY = Math.floor(Math.random() * dHeight);
        $(this).animate({ left: nextX + 'px', top: nextY + 'px' });
    });
});
