Another nice find by DigitalBuzzBlog.

This McDonald’s campaign asks you to watch a :50 YouTube video and look for a certain character hiding in the scene. If you click on the character, you move on to the next level.

It’s actually a little hard at first, so don’t lose your patience the first time to get to the end without spotting Grimace. It’s a neat gimmick for a campaign, and definitely something you could replicate if you have the creativity and motivation.
