"Field of light" photography

Wave of the future or passing fad? The jury is still out: the technology presses forward (they've made them small enough to fit in a phone now!) but I have rarely seen the images utilised.
Either way, here are some of my early efforts; I'm sure I'll improve. Try them out and decide for yourself.

Max & Payne: click anywhere on the image to change the point of focus to that spot.
However as there's no real depth of field in these shots, you can see little difference.
Virgil (sigh). The shot on the right is more of a portrait than a "living photo".
On the left however, my best effort yet. Can you find Virgil laying in wait?
My first efforts, aka: learning the basics.
