Hi and thanks for your question. The materials used here are Kalwall (on the left) which is a thick, fiberglass material that allows light to pass through. On the right is a rice paper laminated door panels. We don't believe either would work well as a back splash, unfortunately. However, you could use sandblasted glass blocks and then light it from below, above, or behind somehow (that would be a challenge.) If you figure it out, let us know!

Lovely, what paint color please are the walls?
