3D Animations In Mid-Air Using Plasma Balls

Posted by kdawson on from the what's-that-crackling-sound dept.

An anonymous reader clues us to research at Japan's National Institute of Advanced Industrial Science and Technology that has produced the ability to make animations by creating small plasma balls in mid-air. The technology doesn't use vapor or strange gases, just lasers to heat up oxygen and nitrogen molecules above the device: up to 1,000 brilliant dots per second, which makes smooth motion possible. When the tech improves it could be used for street signs or advertising.

    It uses high power lasers to heat the air into a "plasma" when running it has the sounds of crackles as mini explosions occur.

    Oh yeah, that's a display I want. Instead of the cat blocking the screen, the cat bursts into flames. How the heck am I going to explain that one to the wife?

      "How the heck am I going to explain that one to the wife?"

      I'd say this:

      Why do you keep talking about this cat, honey? For the millionth time, we NEVER HAD A CAT. I think you need to see a doctor.

      It's a pretty healthy way to help loved ones deal with loss.

      Probably better than telling her that her pussy smells like burnt hair, I suppose.

      Remember the time it fried her cat? And then you lied and said she never had a cat? Then why'd she have the litterbox, Bluesman? Why'd she have the litterbox?

    I think I requested it to slashdot back then too... It got rejected. I think it was replaced with some story about a cool new case mod, perhaps a minor Linux kernel upgrade.

    If something is so important that you feel the need to post it on the internet... It probably isn't that important.

    "Guys!! I just heard that they came up with a way to project images directly in to your brain! Awesome, think of the *commercials*!! " But not in our dreams. Only on TV and radio, and in magazines, and movies, and at ball games... and on buses and milk cartons and T-shirts, and bananas and written on the sky. But not in dreams, no siree.

    That's why I'm working on my Laser Retinal Projector (patent pending) which aims the lasers directly at the retina. Since the eye is sealed system, there's virtually no danger of toxic gases! What's more, it offers a high degree of privacy, and if you're forgetful it can literally etch the images into your mind for life.*

    *Limit of one etch per mind.

    WARNING: Looking directly at the Laser Retinal Projector may cause minor explosions of the eye.

    I like the way you think.

    But what we really need is a way to control mosquitos so that they can swarm to form advertisements. Then we'd get the laser bug zapper for free.
