    i3D is a new app that can create a glasses-free 3D display on iDevices, using a technology known as Head-Coupled Perspective (HCP). Developed by the folks from the Engineering Human-Computer Interaction (EHCI) Research Group, HCP uses a front facing camera to track the movements of a user's head, allowing the app to adjust the display accordingly. The result is a monocular 3D screen that creates the illusion of looking into a box. If the concept sounds a little familiar, it could be because Google unveiled a similar headtracking feature for Ice Cream Sandwich during the opening keynote at this month's I/O event. And by "similar" we mean "pretty much the exact same thing." i3D is now available for free in the iTunes Store and runs on the iPad 2, iPhone 4 and fourth generation iPod Touch. You can compare both iOS and Ice Cream Sandwich 3D generators after the break (Google's demo kicks off around the 16:50 mark).

  • Human Connectome Project maps brain's circuitry, produces super trippy graphics

    A team of researchers at the Human Connectome Project (HCP) have been carving up mice brains like Christmas hams to find out how we store memories, personality traits, and skills -- the slices they're making, though, are 29.4 nanometers thick. The end goal is to run these tiny slices under a microscope, create detailed images of the brain, and then stitch them back together, eventually creating a complete map of the mind, or connectome. The team, comprised of scientists at Harvard, UCLA, University of Minnesota, and Washington University, is still a long way from cutting up a human brain, partially due to storage limitations -- a picture of a one-millimeter cube of mouse brain uses about a petabyte of memory. A human brain would require millions of petabytes, and an indefinite number of years, causing speculation that the payoff isn't worth the effort -- although, we're convinced the HCP wallpaper possibilities are totally worth it.
