Check out the templating system:

    <ul c:if="notEmpty(colors)">
        <li style="color: $color" c:for="color in colors">
            $color
        </li>
    </ul>
    <div c:else="">
        No colors!
    </div>

Not sure if that's been done before but I think attaching "display logic" to specific elements in the DOM is interesting.
