Analyglyphic text is great! It provides an awesome shadown underneath your text solely using CSS!

<style>

h1{
    display: Inline;
    position: Relative;
    font: 200px Helvetica, Sans-Serif;
    letter-spacing: -5px;
    color: Rgba(0,0,255,0.5);
}

h1:after{
    content: "Hello";
    position: Absolute; left: 10px; top: 5px;
    color: Rgba(255,0,0,0.5);
}
</style>
