Better Options display for Size and Color?

Hello,

I've seen the options for Size and Color as a type of "Radio Buttons" and want to include this into my shop.
I don't know how to describe it, so check this example site out: http://www.classicshapewear.com/farmace ... -2483.html and look at the Color and Size Options.

Is there any extension for this?

Thanks

Need to push this..it's very important for me...
