I like those kinds of optical illusions. I wonder if these are the same guy that does the sidewalks. I don't think that bedroom one would be too hangover friendly.
I have a product I print to that is 75mm thick and can be used in garages etc. Have done many bars with it for beer companies and currently doing a "chaulk art" for my entranceway at the shop. Exploded asphalt looking down you see a parkade on level 2 with the noses of my cars sticking out and beyond that on the third level is the subway tracks with a train rolling in.
Digital print - only limited by your imagination.
sorry about that. We have 75mil and 95mil that we use. Most products are done on 95mil, or 1/10th of an inch, for max. Durability
