chameleon fabrics

can we use nano-technology to create a fabric that changes color when a substance of different color is dropped on it? use the fabric on single-color clothes (shirts, t-shirts, jeans, pants etc) to cover stains and spilled liquids. for example useful when you're out and coffee is dropped on your clothes and can't change them. if the stained cloth is white it immediately changes to the color of the coffee stain and voila the problem of bad stain is solved temporarily. want to change color back to white? use a drop of tipp-ex or use other color wite-out to change to different color

Stationary products for nervous people

How about a paperclip that you can give it all sorts of shapes while on the phone but reverts back to its original shape and use after you finish playing with it? The concept is to create stationary products for people who are stressed and nervous and allow them to release their emotions without destroying them. What material could they be made off I wonder. Nano carbons?
