Using code, I drew Hiro's Room and Sanfranstokyo. There are several things happening in this photo: 1) the sky changes color throughout the day to match the sky color with the time and clouds move through the sky, 2) stars appear after a certain time at night, 3) a special star appears at a certain time (second star to the right from peter pan at 11pm), 4)EVE from WALL-E clock changes color at 8:30am to indicate its time for school for Hiro, 5) lights in buildings start to blink at night, 6) you can click on the drawings near the computer to see them on the computer screen.
Picture interacts with time. The snow 'falls' in correspondence to the seconds. The moon changes in correspondence to hours. The character climbs the mountain in correspondence to minutes. when it reaches 59 minutes, the character reaches the top of the mountain and has a white flag with it.
