While it's still up in the air, Doctor Who might soon become an official Lego set.

Two Doctor Who sets were submitted by fans for consideration as part of LEGO Ideas, formerly known as LEGO CUUSOO. Submitted sets are considered to become official LEGO products if the fan-set can gather more than 10,000 supporters. Each set then undergoes review by a team of top LEGO officials to determine the set's potential as an official LEGO product.

LEGO Ideas just announced that two new sets will be officially entering production -- a set inspired by the show The Bing Bang Theory and the LEGO Birds Project, which includes LEGO recreations of a Hummingbird, Blue Jay and Robin Red Breast. Both projects are on opposite ends of the spectrum and highlight just how creative LEGO fans can be.
