KarmaBoard

KarmaBoard delivers the beautiful visuals and click-clack sound of a vintage split-flap signage board, like you might find in a European train station, but without the $3500 hardware investment of solutions like Vestaboard. It runs in any web browser, and includes loads of live feeds (i.e. weather, sports, stocks, airport departures) in addition to your own messages. Send a message straight to your screen, or add it to a rotation playlist. KarmaBoard costs just $9.99 per screen per month, and comes with a risk-free 7-day trial (no credit card required).
