The billboard works by scanning its proximity with an eye-tracking camera, which triggers an image switch on the display panel when it senses someone looking at it. The change only occurs after a brief delay, so that observers understand what's going on, and get the message.

It's a fantastically effective concept, and a brilliant use of technology. Kind of sad, then, that it's probably award bait, and doomed to be a lone installation, according to Copyranter. [Copyranter via Dvice]

New customers will get a LG 225 low-end handset, free activation and shipping, and Amnesty Wireless even offers to buy out subscribers' current contracts with credit up to $175. You get 30 minutes of support calls each month, which means you can ring up and harangue the leaders that Amnesty is targeting. I don't think it means you can harangue your mom for free if you think that the fact she grounded you for staying out late is an infringement of your human rights.

For $29.99 per month you get 200 minutes talktime, plus unlimited nights and weekends and, if you persuade your friends to join, you can call them for free and complain about your mom's behavior.
