For a recent project, we had to make a cinemagram. There was an app released recently that let you take a video and edit it so that only a few things are moving. I tried to do this with the frisbee spinning on my finger, and my headphones moving on my shirt. i couldnt really keep a straight face so the second one didnt turn out very well. on the other hand, the first one, i think, is pretty good. i managed to keep my arm mostly still.
