For those of you who are unable to run my self-inverting pendulum demo, I have posted a screen-capture video of it in action to my YouTube channel. My channel’s URL is https://www.youtube.com/channel/UC7jvewkUPeP777s7HQgKmXA .
The specific demo’s URL is https://www.youtube.com/watch?v=ceboW9ZaF04
If the video appears a bit jerky, this is a video problem; the actual demo runs quite smoothly.
