Model railway advertising display
The world of model railways is full of creativity. This is the latest idea we’re seen to come out the model railway world, perfectly executed by Christoph Ketzler. He’s used tiny screens (0.96-inch (80×160px) or 1.14-inch (135×240px)) as advertising hoardings in his model transport systems, and connected them via WLAN so that the user can upload their own PNG advertising images.
