The GoPro Hero 3 is a frankly ludicrous 'extreme' camera designed capture the most extreme and intense situations imaginable.
Like the London commute.
While the camera - which we love, and have included in our Tech 2012 gift guide - is usually seen on the slopes, in the surf or attached to a maniac in a skate park, it's also versatile enough to use in more creative pursuits.
This clip of the ultra-tough camera documenting life in London over 24 hours is a great example.
The film, Hidden City of Heroes, uses many of the 'extreme' tropes familiar to skate films - weird angles, quick cuts - but it also uses the camera's excellent resolution (up to a massive 4K) and flexibility to awesome effect.
GoPro's UK distributor, Madison, worked with Vertigo Films for the clip. Take a look, above.
