Creating a circular menu with CSS
The following is a way to do it with HTML canvas, and it detects where the mouse is perfectly. It doesn't look the exact same as yours though, and I didn't add the icons or dividing lines (although anti-aliasing allows the background to show through a little between regions creating the illusion of lines being drawn).

Edit - Bug Fix: http://jsfiddle.net/jcubed111/xSajL/2/
With more work you could make the canvas version look the same as your mock-up, my version is only to get the functionality down.
You could also make it look right with css, then overlay a clear a to detect mouse position and provide linking functionality. Of course, then you couldn't use :hover to change the look of the regions.
I've tested in Chrome 19 only.
Here's the full code below in case the link goes down:
HTML:
<a id='link'><canvas id='c' width='224' height='224' onmousemove="update(event);"></canvas></a>
<input id='i' />
CSS:
#c{
width:224px;
height:224px;
}
JS (run on page load and uses jquery):
ctx = $('#c')[0].getContext('2d');
function update(E) {
ctx.clearRect(0, 0, 224, 224);
if (E === false) {
mx = 112;
my = 112;
} else {
mx = E.clientX;
my = E.clientY;
}
mangle = (-Math.atan2(mx-112, my-112)+Math.PI*2.5)%(Math.PI*2);
mradius = Math.sqrt(Math.pow(mx - 112, 2) + Math.pow(my - 112, 2));
$('#i').val("Not over any region");
$('#link').attr('href', '');
for (i = 0; i < 8; i++) {
angle = -Math.PI / 8 + i * (Math.PI / 4);
if (((mangle > angle && mangle < (angle + Math.PI / 4)) || (mangle > Math.PI*15/8 && i==0)) && mradius<=112 && mradius>=69) {
ctx.fillStyle="#5a5a5a";
$('#i').val("In region "+i);
$('#link').attr('href', '#'+i);
} else {
ctx.fillStyle="#4c4c4c";
}
ctx.beginPath();
ctx.moveTo(112, 112);
//ctx.lineTo(112+Math.cos(angle)*112, 112+Math.sin(angle)*112);
ctx.arc(112, 112, 112, angle, angle + Math.PI / 4, false);
ctx.lineTo(112, 112);
ctx.fill();
}
ctx.fillStyle = "#f2f2f2";
ctx.beginPath();
ctx.arc(112, 112, 69, 0, 2 * Math.PI, false);
ctx.fill();
}
update(false);
How to create a radial menu in CSS?
Almost 3 years later, I finally made the time to revisit this and post an improved version. You can still view the original answer at the end for reference.
While SVG may be the better choice, especially today, my goal with this was to keep it just HTML and CSS, no JS, no SVG, no images (other than the background on the root element).

Code
The HTML is pretty simple. I'm using the checkbox hack to reveal/ hide the menu.
<input type='checkbox' id='t'/>
<label for='t'>✰</label>
<ul>
<li><a href='#'>☀</a></li>
<li><a href='#'>☃</a></li>
<li><a href='#'>☁</a></li>
</ul>
I'm using Sass to keep this logical and make it easier to change things if needed. Heavily commented.

$r: 16em; // radius of menu

You can anyways minify this using LESS or SASS, as far as traditional CSS goes, than use CSS Positioning techniques to achieve so..
Demo
Explanation : Here, am using position: relative; container, further nesting absolute span elements which I later position using top and left properties.
If you are creating dynamic menus, than you need to nudge the nth elements using LESS as and when the menu items increase.

</div>Corner Circle Menu CSS and jQuery
The key to creating the menu items is to put them in a circular div and set the circular div to overflow hidden, rotate each one of them and skew them.
Check out this tutorial: http://tympanus.net/codrops/2013/08/09/building-a-circular-navigation-with-css-transforms/
CSS circular menu
Code is Fixed!
So in your .menu attribute, I added the following. These attributes move your menu (.menu) in a fixed position in the bottom left of the screen.
position: fixed;
bottom: 0;
left: 0;
z-index: 998;
I removed the margin-left:-80px; as this caused your menu to warp halfway off the left of the screen when I added the other attributes above. So your .menu attribute should look like this when the proper attributes are edited:
.menu{
@extend %goo;
$width:650px;
$height:150px;
position: fixed;
bottom: 0;
left: 0;
z-index: 998;
padding-top:20px;
padding-left:80px;
width:$width;
height:$height;
box-sizing:border-box;
font-size:20px;
text-align:left;
}
This resulted (on codepen) with your site looking like this. Of course, the gooey menu opens as shown below. I cannot insert the code into stack overflow as there were issues with layout and content. But if you make the changes to your CSS code above, you can see your menu working

The original source that you refer to contains javascript which you didn't include in your fiddle.
I'd recommend you to this awesome menu I found on CodePen that I think you might like.
Please refer this pen from r8n5n.
This pen contains SCSS variables, for Number of items $items: 9 and the diameter of the menu $diameter: 600. You can edit these values to suit your needs easily.
