Thanks! Now I need to steer the style towards something more 'original' :)

When do we get a real 3d screen ?? :-)

It's funny how the depth information in your image is somehow reversed, when
I look at it 2d versus 3d.

They have three-dee screens now... I'm sure you've seen them. I think 
it's just that old Cracker-Jack trick though: a grooved, plastic sheet 
over a spliced image corresponding to the grooves. A person might be 
able to make one themselves at home, provided one has the grooved, 
plastic sheet :) I've got some liquid acrylic.... maybe I should try a 
small experiment...

Have you tried diverging your eyes to it yet? That really screws it up!

This is MEGACOOL. Especially the depth when viewing crosseyed is especially
cool. How did you do that? Is there some math involved to get everything
aligned? Could you do a desktop size (1024x768 or 1600x1200) please?

No.  They actually have another LC behind the main one which can selectively
let the backlight shine through to reach either your left or right eye.
This way you can switch between 2D and 3D in software.

Hmmm it would be pretty tricky, and it looks rubbish compared to the above
method.  This method is used for producing hardcopy 3D photos though.

MEGATHANKS!

With POV there is always math. But this time it was as simple as 
counting by ten. I repeated the hf object along the x-axis and placed 
the light source waaay the heck out there, so as not to cause any trouble.

Um...no time for that, but here's an 800x600 :)

Really Cool!
Only on top of the "middle-row-teeth", the surface looks like a wallpaper to
me. Is that something with my eyes or are there troubles making those
features 3D?

They are 3D, but it can be a bit hard to see for two reasons: #1 - The 
effect is very slight on that part due to shallow details. #2 - Jpeg 
compression really tore this image up, thus 'mixing-up' details.
