Undulating polished wood grains. If that does speak to your heart, go visit another blog. (Just kidding, stay and take a peek!) Recently I came across this project by PROJECTiONE and my heart fluttered.
Each section was cut out of cherry, rotated on it's side to expose different sections of the grain. Then the pieces were sanded, polished, aged, sealed, and installed individually onto a track. Such a stunning work of art! Make sure you visit PROJECTiONE's site to show them some love!
