References to stage plays and props

A great example we looked at for stage plays was War Horse which featured horses,made from wood,which were constructed in such a way that they looked real and would move like a real horse.These people had studied the way horses moved for months to make the perfect movement.
Here are the horses that were used on stage:

Here we see the inside of the model of the horse.Two people help move the horse around by moving the hoves. Both people have to get into a similar rytham if they want to successfully control it.

Here is a link to the video that shows how it works:
