It is not unusual to see a mounted LCD (or LED) panel in the foyer of a school as a way to display school updates and information for students, parents and teachers. Some schools may choose to display a school website, loop a PowerPoint presentation or employ a 3rd party digital signage software (ex. http://www.ucview.com/digital-signage-markets/k12-schools) to help manage how the information is presented on the screen. For those with an older iPad and the means to connect the tablet to an LCD (or LED) display, Status Board (Panic Inc.) may provide a simple and interesting solution for you to display information to your school community.
Status Board ($11.99) is an iPad application that allows the user to create and customize a digital bulletin board that is mirrored to a display. There are a variety of elements or panels that you can use to populate your board. Calendars, weather updates as well as RSS and Twitter feeds can be added as panels and arranged around the canvas of your board. For the more technically inclined, you have the option of creating and sharing your own DIY panels.
