Attached is an image showing my progress so far. I randomly changed some 
brick colors to highlight the spaces between bricks. It was rendered in 
MegaPOV in a single pass and took 5 minutes, 41 seconds to render with 
one core. You can see how the pegs break up here and there. Some of the 
lines also seem to extend over others in funny places. It seems that 
there's always a trade-off when finding edges. The missing line on the 
propeller was my fault; I forgot to change the brick color there. The 
missing lines under the front of the cab were caused by a lack of 
definition in that area.

I'll post an image to help explain how I needed to color the bricks 
differently.
