Here's an interesting audio report on OLPC (it's the first story, and 
runs about 15 min).

The reporter talks to teachers, educators, students and others about the 
laptop and its impact so far - father checks produce prices, mother 
looks up textile patterns, children stay after to school to take 
advantage of WiFi.

I think I hear the text-to-speech program from Squeak, converting 
Spanish text to audio. And, there's the piano keyboard from Squeak too. 
Since there's no video, I don't know for sure whether it's Squeak.
