Dynamic data visualization to highlight a person's *Usual* activities throughout the course of a week. The goal was to help users identify certain times of day or days of the week where they're typically less active. It has a nice side effect (not pictured) of also highlighting the person's sleep habits (areas where it's consistently thin). Each stream represents the activities of an average weekday. A stream's width represents the number of steps taken. The separators within the stream mark 2,000 steps.
You can see more examples of it actually rendered here:
