Pacific Rim features giant robots and giant aliens fighting. The good guys? Jaegers, huge robots controlled by the minds of two pilots. Far fetched? Nope. It turns out that mad sci-fi stuff already exists. Seriously. We were lent a brain-controlled toy helicopter for a couple of hours, and carnage ensued.
The helicopter, by the way, is called a Puzzlebox Orbit, the result of a Kickstarter campaign. Find out more about it here: http://orbit.puzzlebox.info/
