Alas, I cheated on the beams. Added narrow, nearly transparent, cones to the 
centers of those two spotlights. Wasn't even sure anyone would notice that. 
I hadn't dared to try photons yet.

The lights themselves are actual the 'spotlight' type, so they are conical 
in shape too. I used copies of the bowl and glowing sphere as 
'projected_through' objects so I could place the light_source far below the 
actual exit points. Without projected_through I would have been limited to 
using cylinder spotlights, which I did render with for the first one posted, 
and they appear to narrow with height or distance.

That reminds me... I tried to align the light on the left to point straight 
up because the perspective camera was making that look odd compared to the 
old drawing style. In fact, that original really makes the "20th" loom large 
overhead, as though it leans toward the viewer. While putting mine together 
I kept thinking of how many times the artist(s) must have presented the film 
company with rough drafts until they accepted a design. Doing this on a 
computer versus paper or canvas is a great thing, but there's always 
something to be said for hand-drawn pictures such as the ability to create 
it with your own hands. Likewise sculpturing, etc.
