This file is a stereogram. Stereograms are stereoscopic images or animations which combine left and right frames showing slightly different visual angles to allow for 3D perception.
The stereogram uses the side-by-side parallel-view method. The left frame shows the left eye's perspective, and the right frame the right eye's perspective. It might be possible to view this image without a viewing device by diverging your eyes to visually combine the frames, or a stereoscope may be used.
