I attached cardinal little plastic lenses to an OLPC XO and - voila - A $1 picture 100X magnification picture microscope. Here I took some video on top of my XO of a typical laptop screen, the unique XO screen, and written paper. It's interesting for children to see what happens at close. The XO picture microscope could be very helpful, all for example, for looking at water and seeing if any bitty property are swimming in it.
