The paper is set forth here. You need to download the paper itself, plus the videos. You will need the Adobe Acrobat Reader to open the paper. You can then print it, or read it online. In any event, you will need to have it open online even if you print it to play the video simulations.
After you have downloaded the paper and the videos, you should place the paper into a folder (subdirectory) with another folder named videos. You should place all of the movies into that folder.
All of simulations were generated using Starlogo, which is optimized for large, decentralized systems.
