It's a pretty simple game. Just decide what they should call this black wall hook, write it on their Facebook page, and then if you're one of the top six they put your name up in their Copenhagen shop during the product launch.
You can also take part by drawing a design on the product and uploading that too. There will be a prize for the name they choose, the most liked name on Facebook, and the best drawing. The contest ends on March 16th so get naming namers. Here's the fine print.
