After entering your surname and your street address you get to watch a little mini movie of cartoon zombies advancing on your street via the use of images from Google Maps. It was quite cool seeing the undead descending on my house (though my house could not be seen they were congregating several doors down). They then explode with a message saying if you want home insurance then check out the site.
If you want something to smile at then head on over to Home Sweet Zombie at Confused.com and put in your address, is short and funny. I really don't mind adverts when they are this darn inventive!
