iGoogle is Google’s customizable homepage. You can easily create your own and add all manner of tools and toys.
One of the customizable aspects of the page is the theme. Today Google has added a number of geeky themes to their arsenal.
The new collection includes Mario, Guitar Hero, Tomb Raider, Magic the Gathering (I should really write post about Magic at some point), World of Warcraft, Street Fighter IV, Zelda, Mega Man, and Galaga (for those geeks who are looking to kick it old-school) among others.
