Each week, LEGO calls for fans on social media to submit their LEGO creations to LEGO’s social media pages through a HashTag. At the end of each week, LEGO picks the coolest creation and shows it off on their social media pages (Twitter, Facebook, Instagram, Google+, etc.). Showing off fan creations each week is a great way to get the community involved in LEGO building and also to show the possibilities and creativity of LEGO bricks.
