Tuesday morning's Geek Meet in Second Life will be special for two reasons: First, the subject: Keystone Bouchard will speak on virtual architecture -- how design principles in the virtual world will evolve to be be different from real-world architecture.

Bouchard will talk about reflexive architecture in the virtual world, where buildings evolve and respond intelligently to their environment.

In real life, Keystone is Jon Brouchoud, author of the blog The Arch, which explores real-life architecture and design in virtual worlds.

Meet us at 8 a.m. Second Life Time, which is the same thing as Pacific Time, at the Amphitheater at Dr. Dobb's Island.

This should be a noteworthy presentation, not just because of the content, but also because of the medium. We'll be doing the presentation using the beta voice capabilities of Second Life. To participate, you need to be running the First Look client, which is voice-enabled.

This should be quite an adventure. We've never run an event with SL's native voice technology before; previous voice events have used streaming audio over the Internet. We haven't tested the technology, simply because I can't really think of a way to test it. The only way to test it is to do it. This is sort of like jumping off the high dive and then checking to see if there's any water in the pool.

So come to hear an interesting presentation by an architecture pioneer. Or come to hear a disastrous technology test. Either way, you'll be glad you came.
