Kevin Osborn at Bald Wisdom has built on the work of a friend of his who created a Raspberry Pi tablet. Aiming to allow personalisation of an e-paper badge, he hooked up a Raspberry Pi to an LVDS screen (via an HDMI adapter) and a huge button and made a photo booth. There’s a lot more detail on his page. Read how he did it here
