AntiBuger,
хз о чем речь,но возможно имелось в виду,что то типа такого:
<!DOCTYPE HTML>
<html>
<head>
<title>Document</title>
</head>
<body>
<canvas id="myCanvas" ></canvas>
<script>
var myCanvas = document.getElementById("myCanvas"),
context = myCanvas.getContext("2d"),
timeLimit = 15E3,
timeStart = (new Date).getTime(),
canvasSize = 200,
lineWidth = 17,
drawX = drawY = radius = canvasSize / 2;
radius -= lineWidth / 2;
myCanvas.width = canvasSize;
myCanvas.height = canvasSize;
function go() {
context.beginPath();
context.lineWidth = lineWidth;
context.lineCap = "round";
context.strokeStyle = "rgb(0, 106, 229)";
var a = ((new Date).getTime() - timeStart) / timeLimit;
context.clearRect(0, 0, canvasSize, canvasSize);
context.font = '24px "Tahoma"';
context.fillText((100 - a*100)|0, radius, drawY);
context.arc(drawX, drawY, radius, -Math.PI / 2 + 2 * Math.PI * a, -Math.PI / 2, !1);
context.stroke();
1 < a && (timeStart = (new Date).getTime());
timer = window.setTimeout(go, 50)
}
go();
</script>
</body>
</html>
