Nanobliss is a gallery of visualizations of small-scale structures of carbon nanotubes and silicon, created by John Hart and collaborators. The dimensions of these structures range from nanometers to millimeters. The visualizations and the underlying fabrication techniques are new media for art, science, and architecture; and for promoting popular awareness and education about nanomaterials and related technologies. Forms under development include museum/gallery exhibitions and laboratory experiments, and advertising and informational pieces in scientific and popular literature.
