Hi,
I came up with this solution. Hope it helps.
Don't know, why my rotation tip failed - but Warp's hint works always albeit
being less flexible.

This method worked just fine, Norbert!
Thanks again for your help!

Can't see the discrepancy myself, but anyway .. I'd put the eye with its
mount at <R,0,0>
#declare Eye = union {
//the eyeball itself and
sphere { 0,1 scale <1,2,2> translate R*x }
}
and then rotate it into place.
For uniformly random placement this is the way to go:
object { Eye
rotate <0,
degrees(asin(1-2*rand(Seed))),
360*rand(Seed)>
}
For a uniform quasi-grid placement:
#declare H = 1/N;
#declare Z = H-1;
#declare Theta = 0;
#declare Magic = 180*(3-sqrt(5));
#while Z < 1
object { Eye rotate <0, degrees(asin(Z)), Theta> }
#declare Z = Z+2*H;
#declare Theta = mod(Theta+Magic,360);
#end//while

Hallo, Artemia!
The texture of the monster is very interesting: how did you realized it?
Could be interesting with some normal, in order to obtain a vascular system
relief effect.

It's just a color map using a turbulated mandel pattern. I have it set
up as a macro using a color ("Red" from colors.inc) passed as a
parameter, and rbgt 1 to make it layerable. Depending on how it is
adjusted you can get some interesting textures. The image below shows a
convincing raw meat texture (I've forgotten the parameters to get that
texture) but it was several layers using Red and White.
#macro BloodShot(N, T, C, S)
texture{
pigment {
mandel (5000 * RRand(1, 5, N)) / S
turbulence RRand(0.2, 10.9, N)
rotate <0, 0, RRand(0, 360, N)>
translate T
color_map {
[0.010 rgbt 1]
[0.010 C ]
[0.210 C ]
[0.210 rgbt 1]
[0.900 rgbt 1]
[0.900 C ]
[0.900 C ]
[0.990 rgbt 1]
}
}
}
#end

I'm thinking of adding actual veins to the monster's head and body. This
thing is far from being done :-)

Thank you, I'v never dared to use mandel in a texture, but the effect is
very interesting!
