Deep thinkers take center stage

Video introduces "The City 2.0," the initiative that won this year's TED Prize.

The annual TED conference brings thinkers and doers from around the world to Long Beach, Calif., to mingle and take part in a cornucopia of 18-minute lectures and other audiovisual delights. The program focuses on technology, entertainment and design (hence the acronym TED) but it takes in virtually any area of deep thought you can, um, think of.

Each year, TED awards $100,000 prizes for great ideas that could use a little help. One example is the search for extraterrestrial intelligence, which received support in 2009 in the form of a TED Prize to the SETI Institute's Jill Tarter. Just this week, the SETI Institute kicked off a new program called SETI Live, aimed at supplementing the 13-year-old SETI @ Home computer-based search by enlisting living, breathing humans to review radio data.

At this week's TED conference, the big winner was a concept, not a person: The City 2.0, a crowdsourcing clearinghouse that's backed by the Knight Foundation. The City 2.0 is designed to enable citizens to propose ideas to upgrade their own cities, and put them in touch with the resources that can turn those ideas into realities. The TED Prize was announced last December, but details about how the $100,000 in prize money were laid out for the first time during this week's conference. This June, the money will be awarded in $10,000 chunks to the 10 local projects that are judged "most likely to spur the creation of their City 2.0."

Video from some of the other TED events have already been posted to the Web. Check out the music-playing robo-copters that were featured during a TED talk by University of Pennsylvania roboticist Vijay Kumar, and then take a look at these other clips:

X Prize co-founder Peter Diamandis makes his case for the view that we're in an age of abundance.

Environmentalist-entrepreneur Paul Gilding does a reality check on techno-optimism.

Susan Cain, author of "Quiet: The Power of Introverts," talks about being an introvert in an extroverted age.

In addition to the online lectures, TED attendees were treated to a variety of treats, including a project to turn their genomes into a symphony, a "second-a-day" video project and a batch of virtual-reality cyber-illusions. To get a feel for the fun, check out this trio of videos — and for more, take a spin through the TED Blog.

TED attendees provided genetic samples that were processed overnight at Genentech, to produce a "genetic symphony" based on genetic markers. For more about the project, check out the Infinite Variations website as well as this webpage at the Personal Genome Project.

During his TED2012 talk, Cesar Kuriyama showed off "One Second Everyday - Age 30" from Vimeo.

Marco Tempest entertained the TED crowd with a new batch of cyber-illusions. Here's a shorter show-and-tell that Tempest presented last July at TEDGlobal.

Finally, here's a way-too-spooky video from the future: A clip of techno-industrialist Peter Weyland's talk at TED2023, put together to promote "Prometheus," the soon-to-be-released semi-prequel to the "Alien" movie series. Feel the hubris:
