Letterform Comparison

Characters having a common font share geometries and dimensions, but how? Is an "o" symmetric? What's the difference between an "O" and a "0"? If you flip a "b", do you get a "d"? Are lowercase and uppercase the same height? This Demonstration lets you explore the relationships between characters by sliding and reflecting superimposed letter shapes.
