If you open the presentation and the podcast at the same time, you can move through the slides while listening to the talk: a very effective substitute for a video of the presentation.
While editing the podcasts (mainly just cutting up the continuous audio recordings into individual files for each presentation, but also a minimal attempt to amplify quiet sections and remove extraneous sounds - you could spend weeks on that!) I was reminded how much there is in there and how much I would get out of going through them all again.
There's also the recordings of the panel sessions and the final synthesis session. The sound quality is variable for those - because the microphones were being handed around - but again there's lots in there worth another listen.
Photographs from the event are available via this page. I could do with more images or graphics in this blog, so here's one from the first presentation of the workshop, by Wolfgang Hofkirchner.
