So, I decided to re-visit this and do some minor changes on it.  I made this for
the IRTC topic opposites.  (http://allen.emailnuts.com/)  Check on my website
for the first version of the image.

I have made some minor changes to it... finish change on the wood... and
focalblur addition.  Comments and Critique needed, thanks!

    Heh, 'bump'?  ;)  That's the first bump I've seen in here!  :)

   I really like this image, but I don't think the wood texture is quite 
right yet - it think it needs a rotation on either the top or bottom discs 
of wood, and maybe scaling the texture down some more might help (top and 
bottom both needing different scaling). The pillars look good to me, but 
again, they need some variation.

    Also, as it's a timing device, I'd like to see it with some sand flowing 
through. (?)

     Good work.

Yeah, the bumps don't work too well... in moving the thread... but at 
least it got noticed :)

Alright, I'll work on the wood... it seems to be the most difficult part 
to get right.  But that will just take some time to tweak... I'm working 
on another image right now, so I'll come back to that in a few hours or 
a day.

Well, there's a long story on the IRTC Opposites about why there isn't 
sand.  Since space is infinite, and the opposite is finite... I wanted 
to put a timekeeper without its finite measurements... and I couldn't 
make the sand at the time, lol.  I think I'll make another version with 
some sand... that comes after the wood though.

Thanks Steve!

Regards,
Allen

How does sand flow in the absence of gravity...?

Why would there not be gravity in space?

Absolutely, but when you are free floating in space, you don't feel any.
If you don't stand on a surface that is stationary relative to the dominent 
gravity, the sand could'nt flow, as the glass is affected in exactly the same 
amount as the sand.

The only solution to this problem I have found is that there would be 
sand at both the top and bottom of the glass.  This is due to any 
centrifugal forces caused by the spinning of the glass through space. 
You are all totally correct though.

But an Hourglass is a mystical object and the sand is dragged along by the
passing of time.
I thought that everyone knew that :)

 Ah! We have a nice conundrum here, maybe with a bit of casuistry... :-)
... for, maybe, time is dragged along by the flow of the sand through the 
Hourglass!

Now, my solution would be to mount the hourglass in a rotating contraption 
to allow the sand to flow. And don't forget that:
'Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.

Gyre and gimble are the keywords here to build such a contraption as I have 
in mind. Remember also the learned and comprehensive explanation of the 
above by Humpty Dumpty. And finally, look at:
http://en.wikipedia.org/wiki/Mimsy_were_the_Borogoves which tells of a 
haunting short story.
