Мне предложили такой вариант. Не уверен что это работает быстро на слабеньких компах.
<html>
<head>
<title></title>
</head>
<body>
<script>
var mPos = 0;
var cPos = 0;
var bukva;
var step=0;
function moveB()
{
var a;
setTimeout("myBuk = document.getElementById('a1'); mPos = 300; bokMove(myBuk);",75000);
setTimeout("myBuk = document.getElementById('a2'); mPos = 310; bokMove(myBuk);",60000);
setTimeout("myBuk = document.getElementById('a3'); mPos = 320; bokMove(myBuk);",45000);
setTimeout("myBuk = document.getElementById('a4'); mPos = 330; bokMove(myBuk);",30000);
setTimeout("myBuk = document.getElementById('a5'); mPos = 340; bokMove(myBuk);",15000);
var myBuk = document.getElementById("a6"); mPos = 350; bokMove(myBuk);
}
function bokMove(wrBuk)
{
bukva = wrBuk
cPos = parseInt(bukva.style.left);
step = setInterval("dvig();",40);
}
function dvig()
{
cPos++;
if(cPos < mPos) bukva.style.left = cPos + "px";
else clearInterval(step);
}
</script>
