Tom's 20th century

It shows: The decades of the 20th century
This is what you see: The years in 10 year intervals. It's like a road or track, texture (not very graphic).
This is what I could not show better and what is missing: The path bends vertically in a way I cannot display on a 2-D surface. It's 3-D and goes up and down, like a sagging bridge. The 1940s have slots.
