Talking and Walking - another crowd simulation

This one is my second attempt to make a crowd simulation video.

People - a crowd simulation

This is my first attempt to create a crowd simulation video with a software that I am still learning to use.  Crowd simulation has been used in many films such as Worldwar Z. I hope someday I can make something similar or close to what these films have achieved.

As you can see,  the characters do not look real but the way they move is really something that I never thought can be made with computers.
