Floating 1,600dpi 3D projections made by pushing around flecks of cellulose and hitting them with a laser

Physicists at BYU have demonstrated a volumetric projection system that works by using a laser to unevenly heat single cellulose molecules in order to shove them around in 3D space, then painting the positioned molecules with lasers that cause them to glow; by choreographic both sets of lasers, extremely high-resolution moving images can be attained.
