{
    // The "0.4" and "0.6" values make a function such that if one thresholds it
    // at 0.4 the resulting shape touches the borders of the cell horizontally
    // and if one thresholds it at "0.6" it touches the cell vertically. That is
    // the standard convention
    x = sin(x) * 0.4;
    y = sin(y) * 0.6;
    // We would need to divide the following by ("0.4" + "0.6"), but since that is
    // equal to 1, we skip it. The division is required to normalize the values
    // of the function. If those magic numbers change, and they don't sum to 1,
    // then we must divide
    return (x + y);
