Well take a look at the program imgseek. You index your photos, draw a drawing in a simple bitmap paint area, then search for what you painted. Program works well e.g. if you draw a dog... a horse surely will show up. Did microsoft use this program to make their patented image search engine?

One program I tried was gcompris. It is very good for kids. It teaches them how to use the mouse, and has very simple games in it. I have a 3 year nephew that uses it, as his first application, and just used it as had he done nothing else. I would say the levels are from 2-12 years
