Two DNA regions in the style of Salvador Dalí (see "Butterfly Landscape (The Great Masturbator in a Surrealist Landscape with D.N.A.)") with butterflies representing activating histone marks. DNA axis represents a developmental time course with the DNA fragment to the right constantly expressing branches (RNA)

paralleledby decoration with active histone marks (butterflies). Greyish detached branches further represent RNAs expressed by the DNA-fragment to the right at earlier time points. The DNA fragment to the left expresses RNA at one specific time point and is not decorated by active histone marks (even at that time point).
