Also from the TC-RTC comes this image where I used Rune's grass macro, 
with the 'path' variation and the flowers:

This goes from near to far and view remains good. The 3D effect of the 
grass is mainly controlled by the distance between the ground 
height_field and the 'fake' grass, which is a copy of the height_field 
in fact. Note however, that I added some 'real' grass patches.
