Aqui vou mostrar como criar um anuncio com efeito descascar no topo direito do site, anuncio que chama muita atenção, todos ficam curiosos querendo saber o que há por traz daquela casca no canto, quando passamos o mouse ela mostra o que há por traz. 
Vamos lá primeiro vamos criar o arquivo descascar.js segue o código abaixo:

var jaaspeel = new Object();

jaaspeel.ad_url = escape('http://ultraja.com'); //Aqui é o link do anuncio
jaaspeel.small_path = 'http://dominio.com/small.swf'; //aqui o link do swf menor
jaaspeel.small_image = escape('http://dominio.com/small.jpg'); //aqui o link da imagem menor
jaaspeel.small_width = '100';
jaaspeel.small_height = '100';
jaaspeel.small_params = 'ico=' + jaaspeel.small_image;

jaaspeel.big_path = 'http://dominio.com/large.swf'; //aqui o link do swf maior
jaaspeel.big_image = escape('http://dominio.com/large.jpg'); //aqui o link da imagem maior
jaaspeel.big_width = '650';
jaaspeel.big_height = '650';
jaaspeel.big_params = 'big=' + jaaspeel.big_image + '&ad_url=' + jaaspeel.ad_url;

function sizeup987(){
    document.getElementById('jcornerBig').style.top = '0px';
    document.getElementById('jcornerSmall').style.top = '-1000px';
}

function sizedown987(){
    document.getElementById("jcornerSmall").style.top = "0px";
    document.getElementById("jcornerBig").style.top = "-1000px";
}

jaaspeel.putObjects = function () {
// <jcornerSmall>
document.write('<div id="jcornerSmall" style="position:absolute;width:'+ jaaspeel.small_width +'px;height:'+ jaaspeel.small_height +'px;z-index:9999;right:0px;top:0px;">');
// object
document.write('<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"');
document.write(' codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0"');
document.write(' id="jcornerSmallObject" width="'+jaaspeel.small_width+'" height="'+jaaspeel.small_height+'">');
// object params
document.write(' <param name="allowScriptAccess" value="always"/> ');
document.write(' <param name="movie" value="'+ jaaspeel.small_path +'?'+ jaaspeel.small_params +'"/>');
document.write(' <param name="wmode" value="transparent" />');
document.write(' <param name="quality" value="high" /> ');
document.write(' <param name="FlashVars" value="'+jaaspeel.small_params+'"/>');
// embed
document.write('<embed src="'+ jaaspeel.small_path + '?' + jaaspeel.small_params +'" name="jcornerSmallObject" wmode="transparent" quality="high" width="'+ jaaspeel.small_width +'" height="'+ jaaspeel.small_height +'" flashvars="'+ jaaspeel.small_params +'" allowscriptaccess="always" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer"></embed>');
document.write('</object></div>');
document.write('</script>');
// </jcornerSmall>
// <jcornerBig>
document.write('<div id="jcornerBig" style="position:absolute;width:'+ jaaspeel.big_width +'px;height:'+ jaaspeel.big_height +'px;z-index:9999;right:0px;top:0px;">');
// object
document.write('<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"');

setTimeout('document.getElementById("jcornerBig").style.top = "-1000px";',1000);

jaaspeel.putObjects();
