Claim 9:
10. A device to create a cyclically moving pattern of shadows on adjacent surfaces, the cyclically moving pattern of shadows created by motion of a shade and a light with respect to each other, the device comprising:
a perforated cover;
a light source;
the light source creating light, the light passing through the perforated cover;
the perforated cover partially blocking the light to create a pattern of light and shadow on adjacent surfaces;
the pattern of light and shadow cycling as the light source moves cyclically in a linear back-and-forth movement between an first light source position and a second light source position with respect to the perforated cover;
whereby the pattern of light and shadow moves in a manner that encourages a user to match their breathing rate, helping the user to reach a calm state.
