The Light Concept by Owen Song is a 2-in-1 map that also works as a flashlight.
The maps are made up of two papers with a battery in between that allows LED lights to be turned on when electrodes on the paper cover are exposed.
Basically, just roll the map up into a cone and it will light up. This is perfect for long road trips and people who are prone to getting lost in the dark.
