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 method. It has not been indicated which frame shows which eye's respective angle. It is either unknown or the image is made to be usable with both parallel and cross viewing. (If the image is not intentionally reversible, please correct this template by changing the first/method parameter to either "parallel" or "cross".) It might be possible to view this image without a viewing device by either diverging or crossing your eyes to visually combine the frames, or a stereoscope may be used.
