About Jokecam
If your friend's got a new car or just passed their driving test imagine their shock and horror if they receive a joke ZERO speed penalty. Alternatively you may want to make fun of their running or jogging to show zero speed - you can make up a story your phone can work out their running speed which you can email to them. But obviously - don't tweet it to add to their shame!
You take a picture of your friend's parked car (or running athlete), then jokecam adds typical speed cam date/speed/distance text in an LED style font to the picture for you to share/email to them.
Just fun to imagine the look on their face when they open that email.
