Stereoscopic..!!!

# Creating or Eenhancing the Illusion of Depth in an image by means of stereopsis for binocular vision...!!
# Stereoscopy = stereos (solid)+skopeō(to look)...!!
# Two offset images separately to the left and right eye of the viewer...!!
# 2-dimensional images are then combined in the brain to give the perception of 3D depth...!!
# Look at the picture and cross your eyes until you see 3 images. Then focus in on the third image..!!
