You will need something which either bends light rays around itself, or something which "reads" the image behind it, and "projects" that image out 180 degrees ahead of it.

Watch _Chicken Little_ and you'll see a camoflage plate in action.

Bending light is much harder, so with current human technology you will probably have to perfect a camo plate of some type.

Someone in Japan has already made a suit of some type which projects images from behind it, but it's pretty crude at this point.

Good luck,

r979, i'm not sure a camo plate would work. the invisibility suit has to act like a pane of glass, not a video screen that projects the scene behind it. things don't stretch & shrink as you walk by a display window, but they do deform as you walk past a tv screen.

You're right. It's going to need a computer to compensate for distortions. I never said it was going to be easy. Do you have any other suggestions?

no serious suggestions. on the facetious side, i'd consult with a famous illusionist, say David Copperfield if he's available. if he can make the Statue of Liberty vanish, a human being should be easy.

seems more feasible to look for a work around--to seem invisible, instead of actual invisibility--starting with the question of why someone would want to become invisible.
