Drones seem to have three main uses: killing people and recording videos in the present, and delivering DVDs in the future.
Add to that, 'walking your dog'.
This vision of the future - in which the nice 20 minutes you spend walking your dog around the park is replaced with something much more efficient, and unpleasant - is the work of videographer Jeff Myers. It's not a real product, but it's a neat imaginative look at how one might work.
The idea makes some sense - especially for people with limited mobility - though we can't quite see it taking off unless the drone can work out how to pick up the dog's deposits and safely put them in the bin too.
