An approach to replace conventional 5 o'clock shadow for iconography with intelliegent time-aware, algorithm driven shadows using simple sprites. The direction of shadow changes according to the time of the day and based on the direction of the 'hour hand' of an analog clock. This results in natural and enriched user experience on the web.

It is a simple concept derived from the evolution where time was once read looking into the direction of the shadow cast from a pole and inspired by the latest iconography trend of long 5 o'clock shadows. Design must no longer be static. It needs to relate to real-world entity that humans are accustomed to over centuries. </enoughsaid>

######1. Include jQuery and fourshadows.js into your html file. ######2. Place as many icons you need in your HTML with filename in data-icon attribute:

	<div class="fs-icon-l fs-cast" data-icon="filename.png"></div>

######3. Using sample or the placeholder sprite that's provided in the package, create new ones. Ensure the direction of shadows cast as per the sample and to be placed in same order.

######4. Point to the directory where image assets are stored in fourshadows.js settings.

######5. Include this in your CSS file:

	.fs-icon-l {width: 512px; height: 512px;}
	.fs-icon-m {width: 256px; height: 256px;}
	.fs-icon-s {width: 128px; height: 128px;}
	.fs-icon-xs {width: 64px; height: 64px;}

	fourShadows.settings = {
		dimension	: 512, 
		defaultTime	: 5, 
		$el			: $('div.fs-cast'), 
		iconsPath	: 'icons/' 
	}

Use the class accordingly in the markup:

• .fs-icon-l - 512 x 512
• .fs-icon-m - 256 x 256
• .fs-icon-s - 128 x 128
• .fs-icon-xs - 64 x 64

These dimensions can be altered any time. But it would also require you to change properties in CSS for corresponding classes.
