So I just found this site
by checking out the GeekDad
blog over at Wired.com. CUUSOO is a Japanese partner of the LEGO Group. They work with the LEGO Group to produce community supported sets. If an idea submitted to the website gains 10,000 supporters, it stands a chance of being produced as an official LEGO product.
They have some cool stuff, but I really like this one
. To vote for something, you have to register on the site, but it is free. They have sets designed for Shaun of the Dead, Firefly, etc.
