Amazing if they did it using just optical flow.  The ground has multicolored squares.

Same demo indoors, with the same floor pattern.  The people watching have no interest in how it works, just how to sell it.

Could it be that each square on the floor is different so that it actually uses images recognition to figure out where it is?  I think it must be.

Yes.. it  looks like that each square has different colors. But well the image detection is quiet fast :) 

You can check the NodeJS ARDrone how they done the Face detection.

Btw. you should do the same with Arducopter, take 4-5 drones and create a funny schema that the drone will follow
