Crop circles are a shady subject - where do they come from? Are they from space? Well these are!
Space Farm 7 has teamed up with NASA to produce 7 'Maize (corn) Mazes' in celebration of the 50 years NASA has been in space. Each maze (all located in the US), features a complex space themed designed that NASA helped to create as part of a promotion to educate citizens on NASA's work. While NASA isn't really showing us much new here, it's a nice reminder on some of the real technological innovators.
To support the mazes, Space Farm 7 is running a giveaway to win lunch with an astronaut and a tour of the Kennedy Space Centre.
