Having a CMS-based departmental website, it just made sense to display our news items and other content on an LCD screen in our lobby. While the lobby admittedly still needs some renovating, the new screen brightens the space up nicely and promotes our department to students and visitors.
On the technical side, I implemented this project using a custom WordPress page with a jQuery-rotator to display various pages of content. External data (e.g. the college and AP news) are loaded into the screen using RSS and weather is delivered via a Yahoo weather widget. The display is a Sony Google TV.
