Another great invention released at Nokia Betalabs, the Nokia Magnifier turns your phone into a magnifying glass using the built in camera. Thanks Mark for informing me about this.
Oh the camera on your phone must have autofocus in order for this to work, so phones like N95, E90, N82 and other S60 3rd Edition with autofocus camera are supported. The magnifier also allows you to take a snapshot of the zoomed in image so you can see it again next time.
Check out how it works in this demo video.
