Nothing really new with the ride itself, but a test of a motion blur 
script I made.  After trying to find a program to do this and failing, I 
came up with the idea of just making a box with an average of image_maps 
to overlay several images on top of each other.

So then I made the simulator in my roller coaster simulate at 300 fps, 
then rendered the motion blur generating scene, which then resulted in 
this animation.

For those interested, here is my motion blur script.  Its pretty simple.

#declare PREFIX = "bezier";
#declare DIGITS = 5;
#declare SAMPLESPERFRAME = 10;
#declare SUFFIX = ".png";

camera {
   orthographic
   location <0,0,-1>
   look_at  <0,0,0>
   right 1*x
   up 1*y
}

global_settings { max_trace_level 20
assumed_gamma 1
}

box {
   <-0.5, -0.5, 0>, <0.5, 0.5, 0>
   pigment {
     average
     pigment_map {
     	#declare xx = 0;
		#while (xx < SAMPLESPERFRAME)
         	[1.0  		image_map {
			png concat(PREFIX, 
str(xx+(frame_number*SAMPLESPERFRAME),-DIGITS,0),SUFFIX)
   			map_type 0
   			interpolate 0
   	  		}]     // weighting 1.0
   	  	#declare xx = xx + 1;
		#end
     }
   translate 0.5*(x+y)
   }
   finish { ambient 1 }
}
