Four Finger Safe Swipe

This is an initiative to restrict people to use their smart phones while driving.
The Four Finger Safe Swipe is necessary to unlock your device, as soon as you are traveling faster than 15 km/h (about 10 mph).
Since this Swipe can only be performed by someone who's not behind the wheel, co-pilots, or people using public transport will experience only mild hindrance, while drivers won't be able to perform this gesture at all.
This app, while fun, is pretty limited in functionality. However, we hope that this initiative will inspire other app developers to build the Four Finger Safe Swipe into their apps to protect their users.
The Four Finger Safe Swipe source code is released as open source, and will therefore be continuously improved.
Eventually, we expect the manufacturers of mobile devices to implement this, or a better, mechanism into their operating systems.
