Christmas is coming early for political history nerds — a new online exhibit shows 3D models of how the Oval Office has changed over time.

American Home Shield, a home warranty company, says it researched the changes made by each president since 1909 to create the multi-dimensional renderings as part of its 50th anniversary celebration this year.

The company, which had a design team research images from the unofficial and virtual White House Museum and the White House Historical Association, wanted to "look back at the evolution of the most illustrious room in the nation's most famous house," it said in a statement about the project.

The renderings on its website show everything from President Harry Truman's blue-green-filled office, which was the first to have a rug with the presidential seal on it, to the President Ronald Reagan's Oval Office, which had increased the height of the Resolute Desk by two inches to prevent him from banging his knees on the drawers.

President George W. Bush's rug was designed by Laura Bush, and was intended "to evoke the optimism of sunrise."
