Black and White

This idea came up when I thought the white background didn't go with the whole animation I've done so far so I tried to colour the background into black but on some slides I weren't able to do that, and I didn't really want to go through all the trouble of cutting and pasting and erasing stuff again just to change the background black. Then the idea of having it flashing black and white came up, so I just coloured all the ones that were able to be coloured in black in the background and turned the soldiers white and tried to do that so it was like every second slide if not some were every third slide.
