  • benroy, on 12/21/2007, -1/+49Here's a simple way of making a two-dimensional object invisible...turn it side-ways.
  • Supernova36, on 12/21/2007, -1/+11I was bout ready to kill someone if this was that stupid projector thing again..

    (its not, if you were wondering..)
  • GravitySpec, on 12/21/2007, -0/+9Tell me why every godforsaken article has to reference Harry Potter as if it was pioneered by J. K. Rowling... meh...
  • ragipy, on 12/21/2007, -0/+8Just one more dimension to go, can't be too hard. Now back to my 4-d sculpture project...
  • meatmcguffin, on 12/21/2007, -0/+7Still can't find it?
  • swazooe, on 12/21/2007, -0/+5You fool!
  • aladrin, on 12/21/2007, -2/+6At 10 micrometers, it's not a 'cloak', it's a piece of lint. The technology does not scale in size and is useless as a 'cloak' except to things you already can't see from more than a foot away.
  • KyloOb, on 12/21/2007, -1/+5What have you unleashed?! BACTERIA CAN CLOAK THEMSELVES
  • moocow1452, on 12/21/2007, -0/+3Here ya go....

    Still, this is the prototype, so expect some changes in the design between now and launch
  • JWin, on 12/21/2007, -0/+3could have sworn they did this about 15 times over the past 2 years
  • simpleid, on 12/21/2007, -0/+3haaa! :-D lol that was good thinking.
    don't tell the physicist, you'll really disappoint them.
  • inactive, on 12/21/2007, -3/+6So you're only invisible to people with one eye?
  • thcobbs, on 12/21/2007, -0/+2The cloak is useless as its most likely just a demonstration of their ability to control plasmonic waves. The really interesting news was the super-lens technology they've developed using the same abilities.
  • Sjikob, on 12/21/2007, -2/+4"...team has used plasmon technology..."
    Well, that's great and all, but remember that a little girl had to die just so they could create this... No, wait - that's plasmids... Nevermind.
  • Lanefair, on 12/21/2007, -2/+4They won't get far with just one Asian graduate student.
  • wvdavis, on 12/21/2007, -1/+3Go Terrapins!!
  • abuelos84, on 12/21/2007, -0/+2Man if i could digg you five times i would.
  • Klarth, on 12/21/2007, -0/+2Isn't this like the fifth time they've invented this thing?
  • sstidman, on 12/21/2007, -0/+2Yes, this is the definitive invisibility cloak. You should be able to start using it today to sneak around your neighborhood watching various women taking showers. The only stipulation is that the "cloak is just 10 micrometers in diameter". So if you happen to be 5 to 10 times smaller than a human hair, then today is your lucky day.
  • thcobbs, on 12/21/2007, -1/+3I don't know about you, but only a ninja could see something that's 10 micrometers at 1foot away.
  • CondoleezzaRice, on 12/21/2007, -1/+2or better yet, sneak your penis in an unsuspecting woman!!!
  • Feep, on 12/21/2007, -0/+1Video or it didn't...

    Wait.
  • habenneas, on 12/21/2007, -0/+1lynxcache mirror: http://lynxcache.com/cache/Media_A_James_Clark_Sch ...
  • thcobbs, on 12/21/2007, -0/+1He's already got a brick for that.
  • LilJimmyNordin, on 12/21/2007, -1/+2This is fapulous news.
  • alperea, on 12/21/2007, -0/+1After I read TFA before reading comments, I was wondering how many comments would be like parent--thinking it's an invisibility cloak for personal use. It was the first comment. Nice.
  • KragTheDigger, on 12/21/2007, -0/+1ok, so, I am ignorant, and 'Plasmon technology' is a new term to me. At first, I was wondering about it, because, the only form of 'Plasmon' I grew up with is this one: http://www.plasmon.it/index.html . Thanks for teaching me something today,

  • TricK2039, on 12/21/2007, -2/+3Now i just have to get my flying broom.
  • rrbaker, on 01/15/2009, -0/+1U.S. Military receives +4 in savings throw, takes less damage.
  • Gareth1992, on 01/14/2008, -0/+1what he said ^
  • johnnycheeks, on 12/21/2007, -0/+1Super Paper Mario comes to mind...
  • Vulphaestion, on 12/21/2007, -0/+1This is like the 7th different "Invisibility Cloak" I've read in the past year. I'll believe it when I'm using it.
  • beerbarron, on 12/21/2007, -0/+1now my teenage dreams of spying in the girls locker room can be realized! Shame I am to old to perv now :(
  • inactive, on 12/21/2007, -0/+1prick
  • venir, on 12/21/2007, -0/+1http://en.wikipedia.org/wiki/Plasmon

    As I understand it, the reason you can see objects is due to the way light scatters when coming in contact with them. Plasmons are used in some way to keep light from scattering when coming in contact with the cloaking device therefore rendering the object invisible.
  • popjack, on 12/21/2007, -0/+1I'm getting 5 of these, and then I'm going to fool you all into thinking that I have one fewer hairs than I actually do. MWAHAHAHAHA!!!!!
  • NeoNevermore, on 12/21/2007, -0/+1Maybe it's invisible.
  • ThankTheCheese, on 12/21/2007, -0/+1*****
  • inactive, on 12/21/2007, -0/+1Is it just or does that look like Infrared Goatse?
  • Mr.Gone, on 12/21/2007, -0/+0The problem is getting the 40k Gigarams you need to to sync the oscillation overthruster with a proper flux capacitance rating before you insert it into the end line rotary girder assembly. Hell, that's if the Jeffery's Tube holds up. The inverse tachyon pulse matrix would be enough to crack class 20 Unbreakium 90 casing. SHE CAN"T DO IT CAPTAIN, WE JUST DON'T HAVE THE POWER!

    whew.
  • inactive, on 12/21/2007, -1/+1A 2-D invisibility cloak?

    Select, CTRL-X.
  • thcobbs, on 12/21/2007, -1/+1Sure, it will almost completely cloak a 2-D object 1/5 the width of a human hair and is an almost perfect circle and can be placed between nano-sized layers of material in a special geodesic structure.


    Simple eh? Or you could just paint it :)
  • frosted, on 12/21/2007, -0/+0This is about as useful as playing unreal on a 1920s punch-card computer running windows XP.
    Anyone else think that there are better uses for these funds, like curring cancer, feeding the naked, clothing the hungry, or finding a way to stop a fart from stinking in an elevator?
  • NismoZ32, on 12/21/2007, -1/+1This is old information. Wasn't this was on old Digg article?
  • bbtweb, on 12/21/2007, -0/+0freaking phenomenal...
  • sodoh, on 12/21/2007, -2/+2By cloak they mean to make it invisible. Not something you wear. They are talking about stuff at the nanoscale. Actually the article says it is pretty much impossible to cloak anything 3 dimensional or not within their locked spectrum of light.

    So all and all while intresting totally useless.

    If you want actual cloaks check out Japan 4 years ago.

  • NeoSporin, on 12/21/2007, -1/+1Great, more reason to rock a pirate patch on a daily basis.

    Thats the only way we'd fall for it.
  • Drakos, on 12/21/2007, -0/+0Although it's not quite a Romulan cloaking device, it is pretty cool. High five for my alma mater.
  • intoranat, on 12/21/2007, -0/+0It will mainly be use by ninjas against pirates.
  • Matt110189, on 12/21/2007, -0/+0Should be interesting to see what they can do from this. Pretty cool.
