Pisces Function

This function has an interesting level set made up by two fish ("pisces").

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 + (a*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,
