Map With an Interactive Timeline

I love this map of the Digital History of the U.S. The timeline is interactive and each point on the map gives you more in depth information about the event that occurred. I like scrolling through the decades and watching all the little icons pop up and fluctuate in size. It gives a sense of movement and change. Another subtle and interesting feature is the scroll bar for the time line. It is actually also an indication of the average human lifespan. So as you progress through the decades, the scroll bar increases in size to indicate the length of a generation during that time period.
