I found a wallpaper on my computer with a lake view of Hogwarts, which looks like screenshot from Pottermore, but I failed to determine who took the screenshot. Anyhow, I used https://imagetostl.com to convert it to lithophane. The hard part was the fine tuning of the parameters there and during the slicing process. The resulting lithophane is a square with 10cm side length.
The cover photo is a 3D print with recycled PLA in front of my desktop lamp.
