Eine Leuchtreklame (Leuchttafel), die in jede Minecraft-Stadt passt.
First you have to find a suitable place and build e.g. a Netherbrick fence 2*1*4 blocks high. The rest is clearly visible on the screenshot (I took stone steps). One builds now either beacons or Glowstone, whereby beacons fit rather. Then you place an image until it is the desired image (it must fit exactly). I have built day sensors over the highest beacons, these have the “solar cell effect”.
