Just re-found this video and posted it to youtube. It is from a talk I gave in 2006 at the first "International Metagenomics Meeting" in 2006.
I think one may still be able to view videos from the CalIT2/UCSD page here. But I thought it might be better to have this talk on YouTube than at the CalIT site so I posted it ... hope they don't sue me.
Note - I wrote a blog post about the meeting here:
