Photonic Ink Changes Color On Command 34
An anonymous reader submits "According to Nature's report : "A new ink changes colour at the flick of a switch." It now named Photonic Ink, or P-Ink. "P-Ink's iridescent colours depend upon a process called diffraction." "To make the colour of the ink tunable" the team led by Geoffrey Ozin "packs a polymer gel between its stacked spheres" which can change size "when it is soaked in solvent and shrinks when it dries". In addition, it "conducts electricity", and "altering the voltage tunes the ink's colour smoothly through the spectrum." more detail also can found on Advanced Materials."

It might be fun to combine this with piezoelectric plastic film and put it in clothing, so it flashes colors as you move.

Heck with 'skinning' found in most video games, a genaric car could be made to look a little like a porche or in the bad part of town, a toyota.
I'd like to see nascar use this to update sponsors on-the-fly as they bail from the tail car to back up the lead car.

And if it were possible to re-print on the same page, would this mean that newspapers would re-use/recycle themselves? Just plug it into the daily info port, and watch as it reprints itself? It wouldn't be as fun as what i use (The internet for my daily news) but it would be intriguing, and i might go for it just to have a hard copy. On the other hand, it's hard enoguh to keep records as it is- this means there could be documents which cease to exist as soon as you tell them to, no pesky burning involved... hm. I'll have to think about this. When i see colourchange makeup come out, i'm going to scream...

That would be pretty well impossible to bypass, since the decryption hardware would BE the message.
It would also be neat to have a piece of paper that was also a scanner!
