"Since 2008, CUUSOO.com has been partnering with The LEGO Group to create a user innovative design system for people to create and market their own LEGO sets in the Japanese market. This revolutionary business model allowed an amateur user with a passion in deep sea exploration to create the world's first official LEGO set not designed by a professional - the Shinkai 6500." - CUUSOO

LEGO CUUSOO International was introduced in early 2011, so now people all over the world may submit a concept to LEGO Ideas. The LEGO Group will review all projects that reach 10,000 supporters. If an idea passes review it may be chosen for production. So far there have been six models produced:

21100 - Shinkai 6500
21101 - Hayabusa
21102 - Minecraft
21103 - Back to the Future
21104 - Mars Curiosity Rover
21108 - Ghostbusters

On April 30th, the LEGO Group announced that the partnership with CUUSOO Systems has ended and has launched LEGO Ideas to replace it.
