I was in Madrid recently for the TESOL Spain 2008 convention, which was a lot of fun.
I was there presenting the British Council's Learn English Second Life for Teens project, which has been going through a pilot. The slideshow with recording made in Madrid is included below. If you'd prefer to download the audio only, then you can do so here.
I also set up a wiki to support the presentation: http://tesol-spain.wikispaces.com/
