You know, I reckon there's a quid to be made, selling those perspex forms to people who want to detail/superdetail them. Knights of Dice has done something similar in MDF with their Tabula Rasa line. Building shapes, that are a pain to mass produce but can be readily dollied up by folk with the time and inclination. Dunno how cost effective it would be cutting perspex but I suspect there's a gap in the market. Cheaper than a resin building and potentially a better medium to work with than MDF.
