These subway cars are my favorite art galleries. They never stand still; they carry my colors from one end of the city to the other while the world is still asleep. This is my line, my journey to the end of the night. Between stations, rocked by the grinding metal and the hum of neon lights, I sit down and watch my work come alive. Tomorrow morning, thousands of people will step into this carriage, never knowing who left this streak of light in their gray routine. Close your eyes, feel the vibrations. Shall we take this ride together?
