Abstract
A removably attachable optical device includes a clamp comprising an upper clamp member and a lower clamp member. When the clamp is mounted on a mobile device, the upper member extends over a device side to enable an orifice formed by the upper clamp member to be positioned over an aperture of the mobile device. An optical element housing has a portion configured to engage the an upper clamp member. A non-uniform optical element is rotatably mounted to the optical element housing. Rotation of the non-uniform optical element causes light passing through the non-uniform optical element as the non-uniform optical element is rotated to be correspondingly altered to create optical effects.
