I found this in my old videos. Not sure why I never published it until now. This happened several times with an old computer. The screen really was flickering like that, its not just the camera. The minimize and close buttons at the top are huge. I had to do a hard shutdown.
This video was originally available on my Youtube channel "flyoffacliff", which was suddenly suspended in May of 2016. Visit flyoffacliff.com/my-videos for an up-to-date list of my videos.
