After "What does it feel like to invent math", I wanted to do a shorter video, and to experiment with something that lacked narration. Having failed to do due diligence, it was only after I had made heavy progress into the video that I discovered just how unoriginal this method of counting is. Whoops! Nevertheless, I'm glad I made it.
For the first time in one of my videos, I actually filmed something. After using my phone to film my right hand counting to 31, I played around with some image processing techniques. This involved finding the appropriate combination of a Gaussian blur, Canny edge detection, and some more custom operations to thicken and prune the footage.
