Matter Box is a new and innovative approach to advertising. You actually sign up and receive a free, cool box of promotional stuff from well known corporations. Stuff you'd probably never receive otherwise. Stuff that's completely creative, completely free and definitely cool enough to keep around.
They just released the first box last month. Some of the goodies included were over-sized crayon-shaped soaps from Nissan, Play Dough from Sony, and an embroidered arm band from Nintendo. The boxes will be available in the USA later this year, and I've already signed up!
