It's video in a canvas element which overlays a background canvas visualization. It's unclear in the video if P5.js controls both the video and the visuals, I suspect it does.

However, it looks clear to me that a collision detection circle is added to the background visualization, and that the videography is designed to synchronize with that circle. The presenter's head represents the collision zone, where the circle is positioned. It makes the presenters head a "bounce away" zone. It's video/canvas orchestration.

God I wish I could scrub the video, though.

I would like to say it looks very neat. Hoping the guys chime in on how it parallels or surpasses existing tools. The canvas + feature mashup does appear to have great potential. There is limited reason to believe canvas elements are handicap accessible, unless you invest a large amount of time in custom markup configurations which the framework doesn't appear to have addressed.
