Of course, you'd need to add a } to the camera statement. There are some
limitations to this approach, as seen below.  Maybe the y-dimension
thickness of the cylinders could be scaled according to their distance from
the camera using a matrix transformation?  That would fix the fact that
objects look like they're sitting on top of the gridlines (which they are).
 You'd still have the problem of no shadows being cast on the gridlines.

It's sometimes hard to mimic 2D raster graphics with z-buffering using
"real" 3D objects.
