*f(x,y) = fish * eye1 * eye2
*

The function is composed of these three parts:

*fish = (x^3)/3 - x + alpha*y*( -1+ (alpha*y)^2*(1/6 + (alpha*y)^2*(-1/120 + (alpha*y)^2/5040)))*

*eye1 = ( x - xeye )^2 + (y - .5 - yeye)^2 - eyerad^2*

*eye2 = ( x + xeye )^2 + (y + .5 - yeye)^2 - eyerad^2*

where x and y are the domain variables,

- xeye and yeye set the position of the eyes
- eyerad controls the radius of the fish eyes
- alpha controls the scale
*(pun intended)*of the fish body
