Have a look at the interactive map made by Jeroen Gommers.
This interactive aims to give people a sense of how the planets in our solar system orbit the sun. In a simplified graphical presentation the planets are seen orbiting the sun at a relatively high speed. The user is encouraged to grab any one of these planets, drag it around the sun manually and experience the orbit periods of the other planets as they are driven along their orbit at relative speeds, uncovering the ‘interplanetary clockwork’. This alone is the simple essence of the interactive.
