In a step toward electronic newspapers and wearable computer screens, scientists have created an ultra-thin screen that can be bent, twisted and even rolled up and still display crisp text.

The material, only as thick as three human hairs, displays black text on a whitish-gray background with a resolution similar to that of a typical laptop computer screen.

The screen is so flexible it can be rolled into a cylinder about a half-inch wide without losing its image quality.

I wonder what the possible uses for this are. I'm sure they're endless, but are they practical? What is a digital business card other than a novelty item? Why do you need a t-shirt that has a built-in stock-ticker?

The only good use I can readily think of is to incorporate these screens into the military's "smart uniforms" that can tell soldiers their temperature, pulse, O2 levels, etc.

Any thoughts???
