Shadow Telling...

I came across this video on youtube which shows an amazing shadow effect. I really thought this could work somewhere in our piece, maybe for the dragon? or in the army scenes where we could signify lots of people. We could use synchronised movement to denote the army moving forward?
I realise from watching the video that the guy has equipment to make this work effectively but as there are so many of us and only one of him maybe we could try and work this with all of us in a line? I'm not sure if the effect will be the same but it looks so effective I wanted to share it with you and hear your thoughts!

                                           

Let me know what you think!?
