jQuery Efek Nivo Slider Tanpa Plugin

Eksperimen membuat slideshow berdasarkan framework yang Saya buat di sini, untuk menciptakan slideshow dengan efek seperti Nivo Slider. Slideshow ini menggunakan konsep yang mirip dengan Nivo Slider, yaitu mengambil URL gambar untuk dijadikan sebagai latar slice. Efek bergelombang timbul dari .delay() animasi yang Saya set dengan nilai berurutan pada setiap slice:

HTML

<figure id="slider">
    <div class="container">
        <img src="image/slide-1.jpg" alt="Deskripsi slide 1">
        <img src="image/slide-2.jpg" alt="Deskripsi slide 2">
        <img src="image/slide-3.jpg" alt="Deskripsi slide 3">
        <img src="image/slide-4.jpg" alt="Deskripsi slide 4">
    </div>
    <figcaption></figcaption>
    <nav id="slider-nav"></nav>
</figure>

/* Hide all element inside the '#slider' until the page has been loaded! */
#slider .container, #slider figcaption {display:none}
