A few days ago I watched the excellent SF movie "The Transformers" and was blown away by the robots! :-)))  I could swear that the bots were real physical objects not CG figures.
I also watch SG Atlantis and other SF series and can see the diff. between CG and real models but I failed to do that when watching the incredible/beautiful Transformer bots; thanks for this amazing illusion, Hollywood! :-D  (I wonder of course how they did it)
