<i>Playdates for primates</i>

Orangutans MJ (L) and her adoptive son Mahal (C) watch a video on an iPad held up to the glass of their enclosure by volunteer Scott Engel at the Milwaukee County Zoo. Zoo keepers have been using iPads as enrichment tools for nearly a year now and is retrofitting their building with wifi so the playful primates can soon have 'playdates' with orangutans at other zoos using livestreaming video applications like FaceTime.
