Make a DIY 3D "Hologram" Like the One That Brought Tupac Back to Life

Holograms are super cool, but they're hard to make at home. Pepper's Ghost, on the other hand, is a relatively simple 19th century optical trick that looks like a 3D hologram and brought a very dead Tupac Shakur back to the stage. And Joey Shanks is here to show us how to rig up a system to bring Pepper's (or Tupac's)… »5/10/14 1:00pm5/10/14 1:00pm

Breakthrough in Holographic Tech Makes 3D Sets 5 to 10 Years Away

Holographic television sets may be only a few years off thanks to a new breakthrough in 3D technology. Researchers at the University of Arizona said they had made the first updatable 3D displays with memory, a prerequisite for getting any holographic image to move. With the new technology, displays can now be erased… »10/07/08 2:00am10/07/08 2:00am

Ultrasound Haptic Devices Can Project Tactile Shapes Into Thin Air

Researchers at the University of Tokyo have demonstrated a device that can create touchable, creepily invisible floating "objects" using focused ultrasound waves. Though the technology is in the early testing stages, its designers have already expressed an interest in weaponi- I mean, commercializing »9/02/08 8:20pm9/02/08 8:20pm it for possible…
