An image projection device is disclosed having a body defining an aperture that includes a slide frame receiving slot that is transverse to the aperture and a magnifying lens positioned in alignment with the aperture at the front of the body. The image projection device can be attached to a mobile device and uses the camera flash of the mobile device to provide the light source to illuminate a slide transparency. The mobile device can identify a particular slide transparency through information encoded on the slide frame in order to coordinate audio or video output with the projected slide.

A projection light assembly is provided which achieves a multi-theme animation effect. The assembly includes a main mount board, at least one laser light source coupled to the main mount board, a grating group platform rotatably coupled to the main mount board, at least one grating group mounted to the grating group platform, a motor coupled to the main mount board and/or the grating group platform, and a motherboard in communication with the laser light source, the grating group, and the motor. Light generated by the laser light source is transmitted in a light path and projects through the grating group, and the motor drives the grating group to rotate through the light path. Methods of manufacturing a projection light assembly are also provided. Methods of projecting multi-theme animation include providing at least one grating group containing multiple frames, generating light from a laser light source such that the light is transmitted in a light path projecting through the at least one grating group, and driving the grating group to rotate such that the frames sequentially enter and exit the light path.
