This is an example of a navigational device. Each 'arm' can be a link to a different area of your website. The device can also be Javascript enabled, meaning that when you move your mouse over each individual arm, that area would glow, explode, gyrate, twist, turn, spin or just plain disappear. It does not take one long to come to realization that something like this is far preferrable to static text links.
