# Summary of IRC Discussion (March 14, 2010)

• A high-speed imaging technology was discussed that can "freeze" a 6-nanosecond pulse of laser light, capturing images 30 times per second to create 3D models of scenes by tracking how light progresses through space at different depths.

• A PS3 Eye camera was mentioned as a potential low-cost solution for robot vision systems, with discussion about the tradeoffs between resolution, optics quality, and processing requirements for robotics applications.

• A link was shared to a comprehensive collection of data visualization references and tools, including mentions of Gapminder and Infochimps.org as notable data visualization resources.

• There was discussion about optogenetically controlled mice, suggesting ongoing interest in neurotechnology that allows control of neural activity with light.

• A member identified as working with OpenCog (an artificial general intelligence framework) joined the channel, mentioning their connection to the H+ organization.

• Participants discussed various security and privacy topics, including Tor nodes, unusual network connections, and concealed storage devices like hard drives hidden in power strips.
