These third-generation ipods ads have been pretty successful. In this one, young human silhouettes (in black) dance inside an undifferentiated green space, along with traffic-sign arrows, capriciously bisecting or unraveling to the beat of rock music. Then, a female silhouette fills the foreground. For a couple of seconds, the shimmering ipod on her chest comes out the foreground and we read: “Life is random.”
