Waves close wavesVibrations that transfer energy from place to place without the transference of matter. - including sound and light - can be reflected at the boundary between two different materials.

Ben Bartlett created an array of hexagonal mirrors that can reflect the sun's rays in any pattern and can be created by 3D printing. This 3D-printable hexagonal mirror array was created to apply for ...
