Amazing new 3D Holographic Display

I just ran across a cool video of a flying robot playing Jingle Bells on an electric piano. The tempo seemed a bit off, so I clicked through to YouTube to see if there were any more videos. A link for how it works popped up, so naturally I clicked it. Base off of the video, it looks like a human was controlling the robot, so not as impressive as I initially thought. They show some background on “co-pilot” routines that assist the human controllers to keep them from making mistakes. I find this interesting because eventually with AI, these little machines could be completely automated. This reminds me of the creepy surveillance robots from Dark Angel. With special routines to keep these from bumping into obstacles, I can definitely see them flying around our cities sometime in the near future. If you want to see the Jingle Bells video, click through the via link at the bottom. I found this video more interesting though.

A few years ago, the Science Channel aired an episode of SciFi Science, “How to Build a Lightsaber” hosted by theoretical physicist Dr. Michio Kaku. He explained some theories that might be used and developed a rough design that should be “workable in our lifetimes.” Of course almost all of his episodes end up with that qualification. Last month it looks like there was a breakthrough in the hardest part of making a lightsaber work, getting the blade to stop at a certain point.

Although the most prominent uses for controlling the depth of laser cutting are surgical and clinical, Fraser said the team is “very excited about the potential industrial applications,” especially since compared to clinics it’s easier to get new technology into industries.

Unfortunately, the goal is to make the lasers useful surgery, not chopping off alien arms at cantinas.
