Check out this awesome, path-following gesture we made with Google’s Draw a Line: Make your own racecourses, and mimic the body motions of your friends!

This project could be further developed with the option of establishing trigger game objects in a game development platform like Unity. With something like a start and end platform in the virtual space, you could define and time a race between two people along the same path, and really have a racecourse. Alternatively, additional virtual objects could be placed along the path as special trail markers or Easter eggs for your followers to find.
