>From what I heard, I believe I read about something similar in PC 
Underground by B. Bertelson and others. Well they call it a voxel engine, 
but it isn't, I think. They actually texture-map a flat plane, being 
parallel to the ground (which is easy and fast), but draw not only a 
point for each texel, but a vertical line. This is slow due to the divide 
needed for calculating the height and looks ugly to me, too.

Possible Mr. Janczewski is doing something similar. Maybe even without 
proper calculation of the "voxels" height to accelerate it.

PS: Does anyone still have the URL handy? I'd like to have a look at the 
demo, but missed the URL.
