From what I could see at the web page
you provided a link to above, it seems
that these eggs are glued together with
the same type of CSG-glue as I used to
assemle/connect the spheres and tori in
these two images:

http://news.povray.org/povray.binaries.images/12039/
Tor Olav
P.S.: I want my eggs done like this:

No, I foolishly write a patch... copying some code of the sphere and torus.

Me too. In fact I use this:
#macro ovoid (Center, EquatorRadius, MinRadius, MaxRadius, Directrix)
union{
difference{
sphere{ 0,1 scale (MinRadius/EquatorRadius) }
plane{ -y, 0 }
}
difference{
sphere{ 0,1 scale (MaxRadius/EquatorRadius) }
plane{ y, 0 }
}
rotate_to(Directrix-Center)
scale EquatorRadius
translate Center
}
#end
Where rotate_to() is something like Reorient_Trans(); it rotates from +y
to the specified vector.

Do you plan uv-mapping support?

No.
I do not like UV-mapping and I do not want to perform more math
to get a metric along the 2D curve. (a first though makes me believe
I would have to resolve an integral of 3 parts, with the middle part depending
on the parameters... a projection mapping might be worth consideration nevertheless,
so you could have UV mapping if you really want afterall...)
Moreover, my version of pov does not have UV installed anyway!

How'd you replace the drums (presumably) with that??

Nice. Very nice. *Really* like your image. Name of the glue?

That's an interesting egg. Mind posting a version for those of us without 10240x7680
screens? j/k
BTW, what exactly _is_ Mathmatica?
