The lcd flat screen seams to increase the image contrast. Probably because I
keep the ambient lighting low in my study. Will try and preview images in a
different environment before I settle on the lighting settings.

I've had no problems at the tile borders. Sometimes small errors appear when
the maximum Y value of a container is set to low. When that happens I
either hand correct it if it's just one tile, or increase the sample rate
of the macro that calculates the Y values if there are lots of errors. It
also helps to have only a small step in the accuracy between each
isosurface. Most of this is handled with pre parse macros.
