You are going to be given two identical pictures (your photo). You have to paint them in Pop Art style: one of them in black and white, and the second one in colors. Then... we are going to create a 3D optical illution: an agamograph.
The Ben-Day dots printing process, named after illustrator and printer Benjamin Henry Day, Jr., is a technique dating from 1879. Depending on the effect, color and optical illusion needed, small colored dots are closely spaced, widely spaced or overlapping. Magenta dots, for example, are widely spaced to create pink.
To apply the dots to a drawing the artist would purchase transparent overlay sheets. The sheets were available in a wide variety of dot size and distribution, which gave the artist a range of tones to use in the work. The overlay material was cut in the shapes of the tonal areas desired, shadow or background or surface treatment and rubbed onto the specific areas of the drawing with a burnisher.
