Mindshare LA is a monthly event wherein a mixture of technology, design, and community is explored. Awesome guest speakers, good food, open bar, and an incredible range of fantastic attendees who can't wait to meet you. It's every third Thursday and sells out fast, so keep checking the ticket site! I attend this religiously.
BIL:PIL is a healthcare unconference, exploring the next phase of the medical field. It's a fascinating alternative to TEDMED, and the website does a far better job of explaining it than I ever could. I'm unofficially officially coordinating the A/V, since I am a Lady of the Lens.
Last, but definitely not least: PhysOrg.com - Sound imaging: Clever acoustics help blind people see the world So a blind person wears a video camera, which translates its view into an acoustic equivalent which provides an aural version of depth perception to the blind wearer. If this can evolve into a nearly 100% reliable way for blind people to be autonomous in otherwise crowded situations, this would be phenomenal. Question is, would blind people find this practical? How this supplements natural hearing ability is rather beyond me; I'm guessing it exaggerates the placement of sound to emphasize the person's position in their environment.
