Special Painting replicating blocks

A new painting replicating the block it's used on on the available surface, with same size painting got. That could be nice to make secret room and hide things, as well as decorating! (One can simply put a painting from the exterior and another on another block on the interior, and the same wall got 2 different texture.) However that could be expensive to do (needing rare ressources in survival) but a really good option to decorate and make pretty and optimized town, world, adventure!
