Abstract
In one embodiment, a reflecting surface, a gnomon and a dial are arranged so that rays from the sun are reflected toward gnomon such that its projected image is visible on dial. The projected image moves across the dial in response to the movement of sun across the sky, thus providing some indication of time and season. Other embodiments are described and shown.

1) An apparatus for projecting a plurality of images onto an architectural work using reflected rays from the sun or moon, comprising:
- (a) a plurality of reflecting surfaces positioned to be directly exposed to the sun's or moon's rays for at least an instant during the year,
- (b) a plurality of gnomons positioned to be directly exposed to the reflected rays from said reflecting surfaces for at least an instant during the year, and
- (c) a plurality of dials positioned to capture the image created by the projection of said reflected rays on said gnomon,
- whereby said image moves across said dial in response to movement of said sun or moon across the sky.

7) A method of projecting an image on a dial using reflected light from the sun or moon, comprising:
- (a) providing a plurality of reflecting surfaces positioned to reflect light from the sun or moon,
- (b) a plurality of gnomons positioned in the path of the reflected rays from said reflecting surfaces for at least an instant during the year, and
- (c) providing a plurality of dials positioned to capture the projected image from the projection of said reflected rays on said gnomons,
- whereby said image moves across said dial in response to movement of said sun or moon across the sky.
