	The opacity of the "toner" layer should pulse nicely, even when dragging/zooming the map around with new tiles.
	<div id="map" class="map"></div>

	<script>
		var mapopts =  {
			center: [35, -122],
			zoom : 5
		};

		var map = L.map('map', mapopts);

		var watercolorUrl = 'http://{s}.tile.stamen.com/watercolor/{z}/{x}/{y}.jpg';
		var watercolor = L.tileLayer(watercolorUrl, {maxZoom: 18, attribution: 'Map by Stamen, map data OpenStreetMap'}).addTo(map);

		var tonerUrl = 'http://{s}.tile.stamen.com/toner/{z}/{x}/{y}.png';
		var toner = L.tileLayer(tonerUrl, {maxZoom: 18, attribution: ''}).addTo(map);

		window.setInterval(function(){
			// Sine function, phase shifts one radian every sec.
			var opacity = 0.6 + 0.4 * Math.sin(Date.now() / 1000);
			toner.setOpacity(opacity);
		}, 200);
