Online tech superstore Brando has released several different telescopes for different models of cell phones. The telescopes attach to the back of the cell phones, and pictures can be taken using the built-in camera of cell phones. This is great for the paparazzi hidden inside of you, although stalkers could also use this to stalk their prey (not advised).
Cell phones have very low resolution cameras these days, coming in at 2 megapixels and as low as 0.5 megapixels. You can adjust the focus on the telescope, and the unit comes with a neckstrap, the actual unit, and a battery cover. I don't think I am going to be using this anytime soon, although it would make a nice gist for a photography nut who just doesn't have the right equipment. The Sony Ericsson model comes in at $19.
