Here is an ambient campaign from Brazil. [They do really great outdoor out there...] This was for Original Shundi, a Japanese restaurant in São Paulo.
Ninja stars had copy saying "You'll never be the same" and were affixed on vehicles within a 2km proximity of the restaurant. Bonus: the ninja stars were coupons for a free drink. The lunch time crowd increased 80% after the ninja shock-and-awe campaign.
