The backpack is fullt programmable via an app, and is controlled by a remote on the handelbars. There's a full sized version, and also a smaller 'bumbag' (or fanny pack, for our American friends)

The bag, which has been under development since 2010, is set to go on sale in March.
It uses a wireless controller mounted on the handlebar to trigger displays, which can be edited via an Android app.
'The SEIL Bag is designed in order to illustrate traffic signals such as the cruise signal, stop signal and emergency signal directly on the backpack,' said Lee Myungsu, who developed the design.
Pledge levels start at US$149 for a SEIL Pouch, though it'll cost you at least $299 for a bag, controller and app bundle.
The display communicates with the controller using Bluetooth 2.0 technology, and the LED display is flexible and also waterproof - so should survive the British summer.
It follows in the footsteps of the See.Sense we reported on recently, which gives you a smart light.

Two screen sizes have been developed: a smaller, 5 x 9 LED unit that's 115 x 111 x 18 mm (4.5 x 4.4 x 0.7 in) in size and weighs 140 g (5 oz), and a larger 23 x 9 grid with dimensions of 170 x 109 x 18 mm (6.7 x 4.3 x 0.7 in), and weighing 160 g (5.6 oz).
The 135 light unit sports a 2700 mAh Li-ion battery that can run for 12 hours between charges, while the 207 LED version has a 3500 mAh Li-ion battery which can last for 16 hours before needing to be recharged.
