This was an unusual commercial job, I prepared a digital model of this hemisphere and applied a picture of the motif prepared by academic sculptor Jiří Laštovička, the model was then used for production of porcelain litophane. The plate was not part of the job, I made it just for the scenes which are based on the photos of the final product. I really like how it looks, you can see the photos here
