This work represents Barcelona and New York as linked capital cities of contemporary culture. The two skylines connect each other, forming a sort of gigantic segment of DNA.
Left and right side are drawn with both hands, respecting the specific characteristics of the corresponding cerebral hemispheres. So the black part is drawn with the right hand and corresponds to the left cerebral hemisphere: no proportions, no perspective, a lot of visual detail, rational part home of the ego. The red one is drawn with the left hand (right hemisphere): 3D representation, synthetic, dreaming and creative side.
