The Dollar Game (Gino Georgiev)

I recreated the game from the video from Numberphile*, it is not quite done but I made the MVP available here. Rules: Keep clicking the nodes until there are no more nodes with negative values.Distribute sends 1 to all nodes connected to the node clicked and subtracts the sum from it. Collect subtracts 1 from each node connected to the node clicked and adds the sum to it. You only need your mouse to play. By pressing the Distribute/Collect button you change the way of interaction with the Nodes....
