Just noticed through reading Dav Coleman’s blog that James Carse of Finite & Infinite Games fame gave a talk at the Long Now Foundation.
The MP3 is available for download here. The Long Now Foundation suggest you donate something to them to support their efforts if you download.

Sorry for commenting as such, Matt. I met you in Toronto at Digifest 2003 and, through my friend Jyri Engestrom, was recently reminded of you and your good work. Would love to get you blogging on Civiblog. Ping me.
