doesn't work for me. I don't have the most standard setup using Tor Browser, but I don't think I have anything blocked and while symbols do dance around they do not form an image.

Odd, works for me in Firefox, Chrome and Safari. They aren more shapes of text that match the video than images.

I figured it out. It's the anti fingerprinting randomization of canvas data that destroys the image. Though, if it gets drawn on a canvas, is that really MathML?

Edit: I have looked some more into it. It's actually MathML and it seems to trace a video in real time. Somewhere in there is a canvas although I cannot find it in the element inspector.
