Realistic hand shake communicates grip force, body temperature and touch:

Amazing programmable and autonomous helicopters...

Swarm at TED:

DARPA projects on TED

Another amazing video on DARPA projects including brain waves controlling robotics, nanotechnology, and hummingbird drones:

Data Visualization urls to check out...

1. Amanda Cox works for the nytimes, and does many visualizations for them. I believe there are some videos on this page [http://infosthetics.com/archives/2011/12/amanda_cox_talks_about_developing_infographics_at_the_new_york_times_graphics.html]

2. Edward Tufte, the king of information visualization (JC has his books, and he also speaks at conferences). According to his website, he is having one on the 29th of this month. Usually, he only speaks twice a year [ http://www.edwardtufte.com/tufte/]. Check out his videos, search BBC News video, and there are many links that you can check out. This url is the most famous visualization that he is known for about Napoleon’s March [ http://www.google.com/imgres?imgurl=http://www.edwardtufte.com/tufte/graphics/poster_OrigMinard.gif&imgrefurl=http://www.edwardtufte.com/tufte/posters&h=497&w=705&sz=56&tbnid=uQiAQtWuB3vqnM:&tbnh=90&tbnw=128&zoom=1&docid=K5OYdEzmMM3OzM&sa=X&ei=EJ98T_bHIKno0QH02oDuCw&ved=0CFoQ9QEwBQ&dur=387], and he explains it in his book.

3. http://www-958.ibm.com/software/data/cognos/manyeyes/ (this is the site where you can upload your own data, and choose the visualization. The New York Times used to use them, but have since evolved. You might have to check with the person who gave you data, if you can use it publicly. You don’t need programming skills, you can use this website. There was another site called Swivel that did similar things like offer data visualization tools, but they have since closed down.

4. Nytimes urls: http://open.blogs.nytimes.com/2008/10/27/the-new-york-times-data-visualization-lab/

5. Here are some really good examples of data visualizations:

6. Stamen and Gapminder are some companies to check out. I believe Hans Rosling is connected with Gapminder.

7. A little more technical, but definitely worth checking out this library, D3 (http://mbostock.github.com/d3/)

Writing and Speaking by Paul Graham

I really enjoyed reading this essay by Paul Graham, and was happy to read that famous people feel uncomfortable with public speaking...

I'm not a very good speaker. I say "um" a lot. Sometimes I have to pause when I lose my train of thought. I wish I were a better speaker. But I don't wish I were a better speaker like I wish I were a better writer. What I really want is to have good ideas, and that's a much bigger part of being a good writer than being a good speaker... {read more}
