It was jokingly called the “Millionaires’ Dinner,” but I renamed it the “Billionaires’ Dinner.”

That was due to the frothy fortunes that had been made at the time by the Internet pioneers, from Amazon to AOL to eBay. Get it?!?

Well, despite the economic meltdown, there were still a lot of billionaires in attendance at Brockman’s most recent dinner last Thursday in Long Beach. But he recounted to me that the proceedings were a lot more focused on the serious times we are in, as was the whole digerati-packed conference held last week.

Indeed, Brockman now calls the event the “Edge Dinner,” after his lively Edge Web site, where he presides over a variety of eclectic online debates and discussions (in January, for example, the topic was: “DOES THE EMPIRICAL NATURE OF SCIENCE CONTRADICT THE REVELATORY NATURE OF FAITH?”).

Since I managed to miss the fete entirely (embarrassing confession: I fell dead asleep at 7 p.m. and did not wake until the next morning) and could not chronicle it, Brockman allowed me to post some photos from the event taken by him and by former Microsoft research guru and current intellectual property mogul Nathan Myhrvold.

Here are some, and you can see the rest here (click on the images to make them larger):

Google co-founder Larry Page and Applied Minds’ Danny Hillis

Former AOL kingpin and Revolution Health’s Steve Case and Jean Case, Case Foundation

Twitter CEO Evan Williams and Neoteny’s Joi Ito

Nathan Myhrvold, Google’s Marissa Mayer and Nathan Wolfe of Stanford University

Amazon Founder and CEO Jeff Bezos

Microsoft Co-founder Bill Gates and DEKA’s Dean Kamen

New Media Nabobs Tim O’Reilly and Arianna Huffington

But–as many readers have requested–they will all be available in their entirety in this column.

In the less contentious spirit of DEMOfall and TechCrunch50, two demo conferences taking place simultaneously this week, we’re happy to bring you all the demos we had onstage at D6.

Here’s part three of the conference’s most popular demo, by well-known inventor Dean Kamen, who showed off his latest creation, the “Luke Arm” prosthesis.

The state-of-the-art bionic arm looks and feels to its user like his or her native limb.

The video of the demo is in three parts, all of which have been posted today.

In this segment, the DEKA Research founder and Segway creator talks about the FIRST Robotics competition, which Kamen founded to interest young people in science and technology.

In this video, the DEKA Research founder and Segway creator talks more about how the arm’s control was designed and how it was received by a group of injured veterans.

Kamen also talks about the FIRST Robotics competition, which he started to get young people interested in science and technology.

In this video, the DEKA Research founder and Segway creator talks about how he began the project after a visit to his lab by Defense Department officials, who told him that while battleground deaths were down, severe limb injuries were up.

Within a year, the prosthesis was built. In the video, Kamen shows the arm in use, including a man who is able to feed himself after more than a dozen years of being fed by someone else. Kamen also talks about how the arm can be controlled.
