Thanks much for showing me how to avoid the dictionary!

Thanks a lot. That helps.

Although I prefer a solution with exactly one object shown in two displays
my hope has gone and I suppose it will not be realizable. So I'll go to
implement some obj-management which can handle several displays.

By the way: There is no need to convert obj.__class__ to a character string.
Here's your program without dictionary:
################################
from visual import *

x = 300
y = 400
w = 200
h = 200
eyeangle = 0.15 # interocular angle
left = display(x=x, y=y, width=w, height=h)
right = display(x=x+w, y=y, width=w, height=h)
left.select()

b1=box(pos=(-1,0,0), color=color.red)
b2=box(pos=(1,-1,0), color=color.cyan)
a1=arrow(pos=(-0.5,0,0), axis=(1,-1,0), color=color.yellow)

right.select()
for obj in left.objects:
    newobj=obj.__class__()                       # create object in 2nd
window
    for member in obj.__members__:
        if member == 'display': continue # avoid putting into scene1
        exec 'newobj.'+member+'=obj.'+member # set attribute

while 1:
    right.up = left.up
    leftforward = left.center-left.mouse.camera
    right.forward = rotate(leftforward, angle=eyeangle, axis=left.up)

> exec 'newobj.'+member+'=obj.'+member # set attribute

can be written without exec:

setattr(newobj,member,getattr(obj,member))

And thanks much for the additional tutorial! (There are SO many Python
capabilities that I haven't used before....)
