With its three legs it can also be Martian.

thanks ... took a bit of tweeking to get the effect I wanted (slightly
tarnished brass).
texture {
gradient x+y
scale 1.6
turbulence 1
texture_map {
[0.0 T_Brass_1A normal {spotted 0.25 scale 0.04}]
[0.5 T_Brass_2C normal {gradient x+y 0.5 scale 1.6 turbulence
0.01}]
[1.0 T_Brass_1A normal {spotted 0.25 scale 0.04}]
}
}

Jeez, I haven't even done the 'spotted' or 'gradient' thing yet, but yes,
I'll have a go now.
Thanks for the inspiration.
Nice image Jim.

LOL! Well, I sorta knew of this mainly by illustrations from a few hundred
years ago showing it. Idea is for steam to be produced from a fire
underneath and make the upper part spin. Until now, after checking for info
about it, I didn't realize it was basically reinvented from such an earlier
time as 270 B.C. by someone in Egypt. Not sure why Paolo said "ancient Greek
technology", although it has apparently been duplicated since that time.
As to the good rendering shown here, I didn't expect to see the wheel on the
side because I only knew of the device as being just a scientific curiosity
when it was created. That's how it usually gets described, that it wasn't of
actual mechanical usefulness when it was first made and then the much more
recent industrial age put steam to good use.
Hopefully a helpful suggestion: the brass texture might need an environment
surrounding the model to prevent the typical suspended in space appearance.

I added the wheel because it's going in an scene .... the Aeolipile will
power an elevator.
Like Bob said the device was never put to practical use ....
just thought it might be a cool adaption for my scene.

there is a bit of a floor there ... barely visable.
I was going for the object on a turtable, in a black box look for the QTVR
stuff that I'm working on.
72 images looking down at the object, 72 images at the mid line, and 72
images looking up from below the object.
Ciao

I was referring to Heron of Alexandria studies on this kind of tools,
;-)

I was referring to Heron of Alexandria studies on this kind of tools, and
the correct phrase would be "ancient Egyptian technology", sorry!
