I really can't get enough of post-it stop-motion films. Here's one for Brazilian shoe brand Melissa:
It took 350,000 post-it notes, 25 animators, and 5 months to create this stop-motion film shot at the foyer of the Melissa flagship store in Sao Paulo for the "Power of Love" campaign. Passersby were encouraged to write personal messages on the post-it notes.
Here is an ambient ad from Canada for McDonald's "Cool off with $1 Drinks" promotion:
$4,000 worth of Canadian dollars, or "loonies" as the Canadians like to call them, were encased in sheets of ice and shaped into the iconic McDonald golden arches. People chipped away at the seven foot tall ice sculpture for the icy coins.
