I want one of those shirts. :o
I would have an “I’m with stupid” graphic, then when the person in question turned around, quickly switch it to something else. Muahahahah!
Yes, i’m not very evil. 
:smack:
I was seriously, most sincerely, expecting this thread to be about tshirts that look like this.
I’m too geeky even for geeks, aren’t I?
Let’s assume that the clothing is perfectly black (non-reflective) to start with. Since any color is lighter than black, the software just needs to adjust the light emitted accordingly.
(Unless it’s pitch black to start with, then all the lights will be turned off.)
I dont really understand the question. We’re obviously not undersatnding each other, so maybe someone will come along who knows what we’re both saying and present it in a way that makes sense to us.
To get a better idea of what I’m talking about, think of this:
Put your webcam behind your monitor so that your monitor displays exactly what’s behind it. Done perfectly, it will seem like your monitor screen is just a hole and you’re looking through it to your wall.
Or film a brick wall with a camera. Then hang a 60" plasma screen on that brick wall and play your movie on it. How well could someone tell there was a tv there if they were like 20 feet away?
Now instead of a brick wall, just have your clothes display the image of whatever is behind you and there you go.
I dont understand your flashlight question. Maybe a very bright light would wash out the image your uniform is displaying, but you said something about “not” shining the light on the uniform, so I’m lost.
I can think of so many uses for this technology. How about a spandex-like suit that a patient can wear during surgery and it displays the images from an MRI or something. Then the doctor can effectively “see through” the patient and have all his landmarks and everything right there. Or X-rays or anything. He can locate the bullet or tumor he’s removing as if he can see through the skin and knows right wear to go. Something like that anyway. By that time, the technology will be cheap and disposable so he can cut right through it
How clothes that completely change color. Mood Clothes. Imagine your whole outfit turning darker shades of blue as you get sad. Or brigher red as you get angry! Neat! Or a shirt for old people that starts flashing a warning message when one of the portable (and pocket size by this point) health monitors gets a dangerous reading.
Or how about furniture–couches, chairs, loveseats, blankets, pillows, etc–which you can change the pattern and color of as often as you want.
Wow! He’s showing my hospital idea too. Those images are being projected though, right? But he puts his hand in front of the Xray one and there doesn’t seem to be an image projected onto his hand. So I’m not quite sure what’s going on in those videos. The little diagram that is supposed to explain it, just confused me further. Can you explain it?
Its basically a fancy projection set up. A computer is used to adjust the image and keep it updated (so, for example if you’re wearing the suit and the camera is behind you, whomever walks behind you, but in front of the camera, will appear in the projected image). Even a fairly unsophisticated system which just showed randomly moving shapes would make it difficult for someone to draw a bead on you, since they wouldn’t be able to tell how far away you were.
The difficulty in using this for camoflage is knowing what’s “behind” you, since that will depend on which side is “front”, which means knowing where the person is who’s looking at you. For instance, suppose you’re standing in a square room. The wall in front of you is blue, the wall behind you is red, and the walls on your left and right are yellow. Someone standing in front of you needs to see red, so your entire front half would be red, and someone standing behind you needs to see blue, so your back half would be blue. So far, so good… But now what about someone standing to your left? If your front half is red and your back half is blue, he’s going to see a red-and-blue thing against a yellow background, which is not exactly great for blending in. It might be useful if you’re hugging a wall, limiting the directions from which you can be seen, and it could probably be effective as personal “dazzle camoflage”, like Tuckerfan suggests. But invisibility it’s not.
