Derek Huogh - Defying Gravity Dance

Take two very qualified dancers.  Give them a long time to choreograph a dance.  Now, put them in a room that rotates (so, sometimes the ceiling is down).  Now, fix a camera to the room so that it always looks like the floor is down even when they're dancing on the walls.  Then, you have the Defying Gravity Dance.

Watch it.  Your mind will be blown.
