Your income & taxes, then and now: an interactive

From Flowing Data, a link to this interactive chart where you can input your annual income and then see what you would have earned and paid in taxes back to 1913:

From the chart designer:

Having not been alive in the '50s or '60s, let alone filing taxes, I was struck by the high top income tax rate—exactly double the highest tax rate today. It made me wonder: what would my income tax be if I had earned the equivalent of what I earn now several decades ago—or even in 1913, when the current federal income tax program was first introduced? What would the history of income taxes look like through the collective eyes of people in my exact financial situation over the past 100 years?

Neat! Also, a very fast and easy way to discount a present dollar amount back 100 years.
