Ich habe keine obskure Programmiersprache zur Hand. Geht auch HTML5 Canvas?

Code (text/html): 
 
<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<title>YAY YAY HAPPY YAY</title>
		<script>
			var width = 600;
			var height = 32;
			var ctx;
			var text = "HERZLICHEN!".split("");
			var hue = 0;
 
			function redraw()
			{
				requestAnimFrame(redraw);
 
				ctx.clearRect(0, 0, width, height);
 
				for (index in text)
				{
					hue = ++hue;
 
					var color = "hsl(" + ((hue + 10 * index) % 360) + ", 100%, 50%)";
 
					ctx.fillStyle = color;
					ctx.fillText(text[index], index * 18, 24);
				}
 
			}
 
			function init()
			{
				var canvas = document.getElementsByTagName('canvas')[0];
				ctx = canvas.getContext("2d");
				ctx.font = "32px Courier";
 
				canvas.style.width = width;
				canvas.style.height = height;
 
				redraw();
			}
 
			window.requestAnimFrame = (function()
			{
				return  window.requestAnimationFrame       ||
				        window.webkitRequestAnimationFrame ||
				        window.mozRequestAnimationFrame    ||
				        window.oRequestAnimationFrame      ||
				        window.msRequestAnimationFrame     || 
				        function( callback )
				        {
				        	window.setTimeout(callback, 1000 / 60);
				        };
			})();
 
			window.addEventListener('load', init, false);
		</script>
	</head>
	<body>
		<canvas></canvas>
	</body>
</html>
