The Thestral and the "Horseless Carriage"

This build depicts the first time Harry was able to see the Thestrals that pull the "Horseless Carriages" to Hogwarts.  Hermione, Ron, and Neville cannot see the Thestrals and still just see the carriages.  My build farther illustrates this fact.  As you turn the crank on the left side, it spins the Thestral, Harry, and group of Hermione, Ron, and Neville.  When Harry is facing the scene, the Thestral appears as the rest of the group are facing away.  When Harry is facing away and the other characters are looking at the carriage, the Thestral is not visible.  Luna is, of course, already in the carriage with her magazine upside down, and is fully aware of the Thestral.

This was built with parts from my existing collection and was my first big build using Technic gears to create motion.
