A MooTools port of jParallax, seeing as I couldn't find one.
see jParallax for examples: http://webdev.stephband.info/parallax.html
Assuming an HTML structure of:
#HTML
<div class="parallax">
<img src="images/parallax_drops/0.png" alt="" style="width:978px; height:325px;"/>
<img src="images/parallax_drops/1.png" alt="" style="width:987px; height:328px;"/>
<img src="images/parallax_drops/2.png" alt="" style="width:1001px; height:333px;"/>
<img src="images/parallax_drops/3.png" alt="" style="width:1031px; height:343px;"/>
<img src="images/parallax_drops/4.png" alt="" style="width:1067px; height:355px;"/>
<img src="images/parallax_drops/5.png" alt="" style="width:1120px; height:373px;"/>
<img src="images/parallax_drops/6.png" alt="" style="width:1200px; height:400px;"/>
</div>
Then instantiate the class as follows:
#JS
new MooParallax($(document.body).getElements('.parallax'));
