Not our scale I know but have a look at the 2mm Yahoo group, some stunningly good terrain boards for a 2mm FPW game, almost makes me ...
I know what you mean!! Had a look at the Bloody Big Battles report and it looked excellent. 2mm blocks are very tempting!!
I think it may be the way forward for one-off battles such as Langensalza.
We need to "force" the Cigar Battlemats folks to start making terrain mats based on Chris's rules :p
The guys at Deepcut Studio in Finland would probably do it far more economically.
