An artist's representation of the new Brillouin microscopy approach that allows entire light-sheets to interact with 3D biological samples. The artwork features neon-green sheets of light and zigzag oscillations (representing waves) intersecting purple blobs decorated with cartoon-style vibration lines (representing phonons), all against a blue background
