LEGO Ideas

LEGO Ideas is a site created by the LEGO Group for fans to submit their creations in hopes that they will become an official LEGO set. There is a competition among all active submissions and those that get to 10,000 votes are reviewed for possible set creation.
The site also has various smaller building competitions and various other things to help inspire people to build their own creations.
I have a few LEGO Ideas models submitted and they are linked here.
