    sage: from sage.plot.plot3d.shapes import *
    sage: from sage.plot.plot3d.plot3d import plot3d
    sage: S = Sphere(.5, color='yellow')
    sage: S += Cone(.5, .5, color='red').translate(0,0,.3)
    sage: S += Sphere(.1, color='white').translate(.45,-.1,.15) + Sphere(.05, color='black').translate(.51,-.1,.17)
    sage: S += Sphere(.1, color='white').translate(.45, .1,.15) + Sphere(.05, color='black').translate(.51, .1,.17)
    sage: S += Sphere(.1, color='yellow').translate(.5, 0, -.2)
    sage: def f(x,y): return math.exp(x/5)*math.cos(y)

    sage: P = plot3d(f,(-5,5),(-5,5), ['red','yellow'], max_depth=10)
    sage: cape_man = P.scale(.2)+S.translate(1,0,0)
    sage: cape_man.export_jmol('/path/to/a.script')

Then, after downloading jmol, do

./jmol /path/to/a.script

It works perfectly!!! Of course, it needs some doctests...

Try this out, it's awesome:

 sage: from sage.plot.plot3d.shapes import *
    sage: from sage.plot.plot3d.plot3d import plot3d
    sage: S = Sphere(.5, color='yellow')
    sage: S += Cone(.5, .5, color='red').translate(0,0,.3)
    sage: S += Sphere(.1, color='white').translate(.45,-.1,.15) + Sphere(.05, color='black').translate(.51,-.1,.17)
    sage: S += Sphere(.1, color='white').translate(.45, .1,.15) + Sphere(.05, color='black').translate(.51, .1,.17)
    sage: S += Sphere(.1, color='yellow').translate(.5, 0, -.2)
    sage: def f(x,y): return math.exp(x/5)*math.cos(y)
    sage: P = plot3d(f,(-200,20),(-200,20), ['red','yellow'], max_depth=10)
    sage: cape_man = P.scale(.2)+S.translate(1,0,0)
    sage: cape_man.export_jmol('/Users/was/sage-2.9.alpha7/jmol/a.script')
