I have a technical question which pertains to the description of algorithm given in the article. My understanding of the sandpile model (I'm still learning about this) is that it is continuously driven by a steady flow of "sand particles" and this keeps the model rolling. To me, at least, this is not explicitly explained in the article. Some ever so slight fixing of this issue would be appreciated by those who understand SOC better than I do.

I built the model in Python, and indeed you keep dropping grains on the grid. GeneCallahan (talk) 03:10, 10 May 2016 (UTC)
