Transfer data with light?
Have a look at this TED talk by Harald Haas about wireless data from every light bulb.
I think that type of data transfer could be made with just the screen and the front camera. All it takes is an app to do it. The hardware is there.
Maybe there could be modes for different distances? A fast mode for the phone in the next seat on the bus. A slow mode for outdoor messaging? An emergency MayDay mode too, perhaps?
(This idea is called darkMess and is part of the Jolla Helm suggestion for the second device hardware thread).

Update
Saw the Goccia activity tracker at Slashgear and it uses light to transfer data from the device.
One ways Goccia is able to last so long on a charge despite its small size is that it uses LED light sync technology. To synchronize data with the app on the iPhone or iPad, you need to place the Goccia on the front camera of the device and tap it to start synchronization.

Find-Your-Friend Update
My Nokia Blog has posted an article about a Windows Phone app called Over Here that cleverly uses light in a simple manner. Not much data is transmitted but enough of it.

We could have tried something similar at a concert last week, but thought about the flashlight too late. The flashlight would be strong enough even with full lights inside the arena.

Lifi can be received with an off-the-shelf solar panel.
