 Triple Mirror
When you take pictures by XO, its display screen is working as a finder. But it is difficult to see the display when you point the camera at the subject. In such case, a small triple mirror is useful. The cost of triple mirror is about one dollar or less. It is a good activity for kids to make their own camera adaptor by themselves.

 Origami Finder
It is possible to make a finder from paper using origami technique. It is inserted into the USB port. It is same as other ideas.
 Paper Viewfinder
Probably the cheapest and simplest solution, requires only one 6 cm x 4 cm piece of paper and a piece of adhesive tape. Has the additional advantage that it can be left on the XO, folding down for storage.
