Originally for visions of the future I thought I'd go with a 
futuristic city with trains in glass tubes etc, but decided that 
was way too cliched.  

So instead I went with something....... equally cliched!

"Drones" started out on a smaller scale, with only one person 
being in the frame, but as I made the scene, I thought 'wouldn't 
it be cool if there were heaps of these people plugged into "The 
System"'.  So, here it is.  Unfortunately I had to sacrifice some 
of the detail, lose some of the wires into people's brains etc, 
and you can no longer see the grusome spikes going right into the 
Drone's heads.  Pity.

If the scene were to be rendered all in one go, there would be 
over 100 lights (!) and 3 million polys (!!) which is just a tad 
to much for my P200.  So instead I split it into chunks, rendering 
the furthest elements first, setting that render as the background 
image, rendering closer stuff, setting that as the background, and 
so on.  The high poly count is due to the scale and detail of the 
scene, but also admittedly the objects are a little over engineered.

Very light fog was included to give the impression of distance (and
therefore size), and glowing particles rotated and motion blurred were
added to the energy field for some extra interest.  Virtually no post
production took place (fixed up a few edges though), and the men and 
women are simply PoserPeople.
