If you've ever taken a spin on a motorbike, you'll have either felt the exhilarating rush of speed and danger, or the terror of imminent injury, or more usually both.
Either way, you'll definitely understand how useful it would be to be able to see behind you, without turning your head.
The Skully Motorcycle Helmet aims to fix that. How? Well, cameras mainly. But there's some engineering magic in there too.
Check out the video below.
Best Cameras 2014
Sony RX100 III(01 of09)
The Sony RX100 III is Sony's flagship compact camera. Small enough to -- realistically -- fit inside your pocket yet powerful enough to compete with cameras twice its size. With a 20.1MP 1-inch sensor and a 24-70mm f1.8-2.8 Lens this is the ultimate holiday camera.
Panasonic Lumix GX7(02 of09)
The Panasonic Lumix GX7 is the company's flagship micro four thirds camera. With a design that's inspired by Panasonic's old cameras it feels both retro yet also extremely premium. Combining Panasonic's hugely powerful imaging processors with a truly versatile lens the GX7 can focus in as little as 0.06secs.
iPhone 6 Plus(03 of09)
Despite being only 8MP Apple have carefully and meticulously crafted a camera so capable that it proves numbers really aren't everything. Yes, we know it's not a camera, but that lens bulge is probably one of the most-used cameras in the world. With an f/2.2 aperture and Apple's own Focus Pixels the iPhone 6 Plus is capable of taking some seriously sharp photos, even in low-light. It'll capture 1080p HD video as well as 240fps.
Sony QX1(04 of09)
The Sony QX1 is the next-generation 'Lens Camera' for your smartphone. This latest version takes the abilities of the lens camera a step further by now featuring an 'E Mount' letting you swap out lenses without having to buy separate modules. The QX1 contains a 20.1MP sensor and comes with a 50mm lens attachment as standard. Of course if you want to go full pro you can start buying up any Sony lens that supports the E-Mount turning your smartphone into a fully-fledged DSLR.
FujiFilm X20(05 of09)
There's a lot to recommend in the X20, especially if you're looking for a more old-school shooting experience in a digital compact or wantan optical viewfinder and can't afford the X100S.
Olympus XZ-2(06 of09)
This camera is all about the night-performance. Its 12-megapixel sensor is decent in most environments, it ones with a range of good filters and effects, and image processing taken from the latest PEN cameras. Oh, and its 3-inch tilting screen is a great feature. But it's the camera's performance in low-light that really stands out - where it's among the best we've used. Still, at around £480 it's pricey compared to its nearest rivals. (£349 at Amazon)
Canon EOS 650D(07 of09)
This full DSLR has am 18-megapixel sensor, has amazing image quality and genuinely intuitive touchscreen controls. If you can afford the £560-ish for the body alone, never mind the lenses and extras, you'll not need to buy another camera for a very long time. (£524 at Amazon)
Samsung Galaxy Camera(08 of09)
The Galaxy Camera is unique, in that it's essentially a mid-range compact with an Android phone slammed into the back. Yes, it's weird, but it does mean you can use your regular Instagram/Facebook/Twitter apps with a camera as good as most point-and-shoots on the market, and upload them via 3G or WiFi. Which is a great feature, and for some worth the purchase. (£294 at Amazon)
Fuji X100S(09 of09)
The classic styling of Fuji's top compact camera masks its serious quality under the hood, with 16.3 megapixels, DSLR-quality pictures and a lightweight, slim body that won't get in your way when shooting on the street. Fuji claim a 30 per cent improvement in signal-to-noise over the previous generation X100. (£1,000 at Amazon)
