It's hard to keep track of all the changes in grand prix car design since Formula One began in 1950. This minute-long video tracing the lines of each year's cars makes the whole history seem so simple, and so very beautiful.

Put together by Ruf Blacklock, the video is actually quite multi-dimensional, even though it just consists of animated line drawings. You see the quick-acting revolutions (rear-engined layout, wings, ground effects, high noses), and you see the longer spells where the cars slowly refine over a stretch of years.

What surprised you most about the changes that happen in the video (and in this companion infographic)?

(Thanks to everyone for the tips!)
