Some clever geeks souls at the University of Washington have used some pretty serious tech to allow themselves to make a flexible and safe -- don't they always tell us that? -- contact lens with a built-in circuit and lights. Uses for it are all right out of a James Bond film, seeing a caller-id pop up as if floating in mid air, web browsing, and of course its application could extend to cars, gaming, and just about anything you can dream up that uses a display. No word on what type of communication gear they could use, but hopefully security will be top notch as having somebody hack your eyes as you're out and about would be a pain.
