Those are so cool. I think I like the gills the most, but it's a tough call. Being math-defunct myself, most of my attempts at stringing together long made up equations have resulted in mostly uninteresting results. Do you know of a way to get it to recognize Sin or Cos in an equation? If I could find a way to do that, it might spice things up, but it calls me an idiot when I type them like that.

I'm not sure if this will help at all, but hopefully it's a good starting point.
Here's the expression for the terrain model (with a limit of 3 (x,y &z)):
cos((2*x)*(x + y + z +1))*sin((2*y)*(x + y + z +1)) + cos((2*y)*(x + y + z +1))*sin((2*z)*(x + y + z +1)) + cos((2*z)*(x + y + z +1))*sin((2*x)*(x + y + z +1)) - .25*x*x*x - .25*y*y*y - .25*z*z*z - 2.5
You can break it down to
[cos x(expression) times sin y(expression)]
plus
[cos y(expression) times sin z (expression)]
plus
[cos z (expression) times sin x (expression)]
plus (or minus)
a variable,
and maybe you can start to get some pretty cool sh*t happening.
For the "expression," you might start by using the formula for a sphere, x*x+y*y+z*z-1.

@ana Thanks! I've been dabbling with different low-end 3D programs as a hobby off and on for a little over twenty years (late '80's). I've only used the app for these models (MeshLab) for a few months.
