Post-it note art

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.
