А в svg и css3 трансформации интереснее .

(function(){
		var a = 0;
		var image = document.createElement('image');
		image.src = 'http://javascript.ru/forum/images/ca_serenity/misc/logo.gif'; // снова 
		image.onclick = function(){
			image.parentNode.removeChild(image);
			clearInterval(intervalId);
		}
		with(image.style){
			position = 'fixed';
			top = '50%';
			left = '50%';
			margin = '-38 0px 0px -162';
			cursor = 'pointer';
		} 
		document.body.appendChild(image);
		var intervalId = setInterval(function(){
			a += .05;
			image.style.MozTransform = image.style.WebkitTransform = image.style.OTransform = image.style.transform = 'rotate(' + (Math.sin(a) * 20) + 'deg) scale(' + (Math.sin(a*4) * .1 + 1) + ', ' + (-Math.sin(a*4) * .1 + 1) + ') ';
		}, 40);
