Beautiful 2-in-1 3D Lenticular Picture, showing two different scenes of Tropical fish, depending on which angle you look at it from. Only one image is shown of the Fish scene, but both scenes are really beautiful. and appear as if the fish are swimming along.
Lenticular Pictures have Stereoscopic effects which gives a slightly different view as you move in front of the picture.
These pictures have a lot of depth which creates a 3D effect without requiring special glasses. Difficult to describe but truly amazing when seen.
