He has produced a film that colorizing old footage from the First World War. In addition, he has slowed it down. That is, if you've seen film footage from the early 20th Century, you'll notice it is always fast, as if it's been sped up. That's because of the development of technology in moving pictures from when it was filmed to later playback.

This is the 100th anniversary of the war, and has received scant little media or popular coverage. As we approach the 100th anniversary of when the guns fell silent, perhaps this will instill a little curiosity on the part of moderns to look back and remember, and learn, from that period in history.
