thank you!

I suppose it would be possible, as it's one big trianglemesh
As soon as I find the time to finish the macros, I'll see what I can do :)

the PatchAt-macro is actually more like a function that is used by the 
greebles-system.  The macro accepts 2D-coordinates as input, and outputs the 
3D-coordinates corresponding with the given 2D-coordinates
