You know what's crazy? Here, they sell those phone booths which actually fit in your pocket. And mine even got an integrated camera obscura. That means I could produce a portrait of me within seconds and share it over the Hypertext Transfer Protocol so you could look at in America while I am still in Switzerland. magic, I know.
That takes effort. I'd have to find my phone or digital camera, take a picture, usb it to my computer, host it somewhere, then post it. isight lets you take a pic from where I'm sitting.
