Creative Advertising

I have decided to make some advertisements for my final project, about time i actually started doing something and stopped concepting and researching! I love adverts that use the space around them as a feature of the work, here are some sites and links...
http://www.toxel.com/
http://adshunters.com/

You'll find heaps more great examples on these sites but these are just a couple that caught my attention :)
