DESCRIPTION
Eight white and gray, three-dimensional disks in three rows float on a powder blue background. In each corner is the convex side of a disk, with the numbers "01" in black in the upper left, "02" in blue in the upper right, "03" in orange in the lower left and "04" in green in the lower right. The remaining four disks are concave and contain images of a green smartphone, a blue tablet, an orange computer screen and a green closed envelope, each with tiny, illegible text below in the corresponding color. There are gray shadows along the rims of convex disks and on the background beneath the concave disks.
