1. Red indicates happiness, blue indicates unhappiness. White indicates little change in satisfaction, or near-zero happiness. The size of a cell represents satisfaction. The brighter the color, the greater the change in satisfaction.
2. Same as 1, with black indicating little change in satisfaction.
3. Smiles indicate happiness, frowns indicate unhappiness. The fatness of the face represents satisfaction. The bigger the smile (or frown), the greater the change in satisfaction.

1. Neighborhood Radius. The radius of a cell's neighborhood. A cell's neighborhood consists of all the cells with which the cell can trade.
2. Max Trade Size. The maximum number of tokens from each category (x, y, z) that a cell can give away in a single trade.
3. Max Endowment. The maximum number of tokens from each category (x, y, z) that a cell can be initially endowed with. Endowment is randomly determined, so this sets an upper limit.
4. Fairness. The degree to which trades initiated by a cell must be fair. A fair trade is one that results in the same amount of happiness for both cells. A trade that makes one cell happy, while making the other cell less happy is unfair. Note that a cell's fairness applies only to those trades that it initiates. A cell with a fairness of 1.0 may still make an unfair trade with another cell, if the other cell is the one initiating the trade.
5. Dissipation/Production Rate. The rate at which a cell consumes or produces tokens. Negative numbers are dissipation rates; positive numbers are production rates. A cells tokens are decreased or increased by this percentage with each round. When set to zero, the cell neither produces nor consumes tokens. Note that if a cell runs out of tokens, it can no longer produce tokens.

1. Average Satisfaction (S). The average satisfaction of all cells in the universe.
2. Average Happiness (H). The average happiness of all cells in the universe.
3. Omega (W). This statistic is an attempt to measure the complexity-and-organization of the universe. The current measure is rather crude, and a better measure is being developed. Contact the author for more information.
