Autostereogramming it doesn't help me lol
If it's perfect, the overlapping regions just merge in color, i.e. the cat's paw becomes off-white. If it's not perfect, I still have to attend to which parts are popping in and out. In both cases I still have to compare the merged view to the left and right hand sides.
Although it is very nice for illustrating each eye's contributions to the merged view. Just not an attention-saver.
