Scientists attached 3D glasses to cuttlefish to better understand the molluscs' visual perception as it relates to their ability to attack prey. They were treated to 3D screenings of shrimp while the University of Minnesota researchers studied their behavior. I wonder if, like me, the 3D movies gave them headaches. From the University of Minnesota:
The (shrimp) images were offset, allowing for the researchers to determine if the cuttlefish were comparing images between the left and the right eyes to gather information about distance to their prey. The process of comparing the images is called stereopsis, and is the same way humans determine depth. Depending on the image offset, the cuttlefish would perceive the shrimp to be either in front of or behind the screen. The cuttlefish predictably struck too close to or too far from the screen, according to the offset.
“How the cuttlefish reacted to the disparities clearly establishes that cuttlefish use stereopsis when hunting,” said Trevor Wardill, assistant professor at the Department of Ecology, Evolution and Behavior in the College of Biological Sciences. “When only one eye could see the shrimp, meaning stereopsis was not possible, the animals took longer to position themselves correctly. When both eyes could see the shrimp, meaning they utilized stereopsis, it allowed cuttlefish to make faster decisions when attacking. This can make all the difference in catching a meal.”

Physicists at BYU have demonstrated a volumetric projection system that works by using a laser to unevenly heat single cellulose molecules in order to shove them around in 3D space, then painting the positioned molecules with lasers that cause them to glow; by choreographic both sets of lasers, extremely high-resolution moving images can be attained.

Americans can legally manufacture an assault rifle for personal use without registering it, so Daniel Crowninshield figured his paying customers could push the button to start his milling equipment and claim they made the AR-15 themselves. Feds disagreed. Read the rest
The only thing at Hypernom.com appears to be a 3D fractal cage. You can move toward the edge with the WASD and arrow keys. But as you approach it, a new level of detail pops in and you seem no closer to the perimeter. Approached as a game, there is a "trick" to escaping—but I'm not sure you're supposed to. Press numbers to change the forms that bind you. There are all sorts of things going on like this. Read the rest
