    The full talk seems to be at <a href="https:&#x2F;&#x2F;au.cloud.panopto.eu&#x2F;Panopto&#x2F;Pages&#x2F;Viewer.aspx?id=fe0c3b34-90d9-4853-94db-b4b3009fd277&amp;start=12580" rel="nofollow">https:&#x2F;&#x2F;au.cloud.panopto.eu&#x2F;Panopto&#x2F;Pages&#x2F;Viewer.aspx?id=fe0..., but with a confusing interface (text chat flying by at speed, and no actual video of Alan, though you do get a prolonged view of a whiteboard). Maybe there&#x27;s another copy that exists or will show up somewhere?

      Yes it&#x27;s a pretty klunky interface. Easy to miss that there are multiple camera icons to the right of the time slider, and you can switch to see different feeds like the speaker or their slides. It&#x27;s still kind of hit or miss with some of the speakers, but at least Alan got a chance to test things out and debug all the glitches before his talk, so he didn&#x27;t end up repeatedly interrupting himself!

      Here is the full list of links from the video description to other related and interesting topics.

      I can highly recommend smoking a joint and watching James &quot;Doctor Chaos&quot; Crutchfield&#x27;s &quot;Space-Time Dynamics in Video Feedback&quot; film, which he made at UC Santa Cruz in 1984, building on Ralph Abraham&#x27;s video feedback experiments there in the 1970s:
