Through this week, we continue our countdown of the best work of the year in TV/Film, Print/Outdoor/Design and Interactive (IX)/Integrated/Social. See all the Best of 2014 so far here.

At #4 in Interactive/Integrated, FCB Brazil conceived this brilliant integrated campaign that made lives easier for beach-going families, for Nivea. It included a print ad that could be turned into a bracelet that parents could place around their children's wrists. The bracelet triggered a mobile app that would alert the parents if their children strayed beyond a pre-set boundary--a perfect way to give mom and dad a chance to kick back on the sand while the little ones went off to play.

Original Post:

Any parent who's ever visited a crowded beach knows that, second to your worries about sunburn, having to keep a constant eye on your kids is also a sure-fire way to make the day less than relaxing. So Nivea Sun, and agency FCB Brazil, came up with a clever idea for the Brazilian market: create an ad that doubles as a device for keeping track of children. The magazine ad contains a strip that can be torn out and used as a bracelet; there's also a code for parents to link to Nivea's smartphone app NIVEAProtege. Once the kid is wearing the bracelet, the app will alert parents if they stray beyond whatever pre-set boundary the parent has selected.

The campaign took home the mobile Grand Prix at Cannes this year. Read the adage.com story for details
