Courtesy of Mark Tarbatt from Generator for his tweet on the bus shelter that watches.   This Amesty International bus shelter ad uses eye tracking technology to switch the ad content dependent on whether someone is looking at the ad or not.  Its a really nice evolution of a static medium and has a feel of the Minority Report about it.  When you look you see a regular couple, when you turn away it switches to domestic violence reflecting what happens in reality in many homes.

This is a clever execution but this eye tracking technology could be used in lots of different on street type applications outside of bus shelters e.g. installations in shop windows, on street art pieces that could literally have a conversation with some using eye contact.  Nice one to add to the mix – wond
