Ok, so only loosely related - I find new matrix headlamps on cars to be pretty intriguing. Basically they have an array of lights that are focused like pixels, and they can turn off the pixels that would blind others.

Wonder if this kind of stuff can trickle down to bicycles and motorcycles and you only light what's important in front of you. This could be to light more stuff so you can see it, or less stuff and save power while seeing what's important.
