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 type="text/javascript">
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);
