The site is a single-page-scrolling giant timeline, illustrating the history of Ace Hardware. Each 'page' is an interactive representation of a year in Ace's history. Users are encouraged to drag the middle slider from left-to-right to see the historic imagery contrasted against the modern.
This is the same page as above, on a tablet-sized display. Instead of a user-controllable slide, the slider "jumps" between the before/after/middle positions. The years are now represented by dots at the bottom of the screen, instead of stacked on the left side.
