This massive undertaking is an accomplishment to be truly proud of and we're ridiculously jealous that we didn't think of it first. If you take a close look at the tiles on the tabletop, each one is a singular tile that has been repainted to coordinate with a periodic element. You can use ceramic paints found at your local craft store to get a similar look at home.
Maybe a bench and table set isn't what your home needs, but how cool would a periodic table backsplash in a bathroom be? Will all the science nerds in the house please stand up!
