Patent ID: 8528218

Claim:
A sundial comprising: an at least substantially spherical curved reflector, wherein the at least substantially spherical curved reflector is at least partially transparent, and wherein the at least substantially spherical curved reflector comprises at least a portion that is at least partially reflective such that light from the sun can pass through a surface of the at least substantially spherical curved reflector and be reflected off of an internal surface of the at least substantially spherical curved reflector to reflect an image of the sun from the internal surface; and a dial face positioned within the at least substantially spherical curved reflector and comprising a front surface and an opposite rear surface; wherein the at least substantially spherical curved reflector and the dial face are rotatable together such that an angle of the dial face with respect to a vertical plane may be adjusted to allow for use of the sundial at a plurality of different locations each having a different latitude; and wherein the sundial is configured to permit viewing of a reflected image of the sun on the dial face, and to provide at least an approximate indication of the time based on the position of the reflected image of the sun on the dial face.
