GOING APES: Several zoos are experimenting with computers. Six orangutans at Miami's Jungle Island use an iPad to communicate and as part of a mental stimulus program.
WHAT THEY DO: 8-year-old orangutan twins draw, play games and expand their vocabulary. Their family's teenagers like the hand-held computer tablets, too, but the clan's elders show no interest.
HOW IT WORKS: The software was originally designed for humans with autism. The screen displays pictures of various objects. A trainer then names one of the objects, and the ape presses the corresponding button.
