Dan de Board let us know that the presentation a few Bungie employees gave at this year's Vancouver Siggraph conference can now be experienced through a handful of slides at RealTimeRendering.com. At a quick glance, it looks like there's a lot of interesting stuff in there, including a glimpse at the testworld spaces used to prototype incoming content. Be sure to click on the images or "preview" in the PowerPoint to see the actual animations!
