That's a great offer Njeneb! I earlier had some guys modeling these houses, but somehow it didn't work out to perfection. These archeological people are quite fussy. Please give it a go, if you have time, I'd be very obliged!! I'll mail you some photos.
Anyway, here's my XFrog cow, quickly put up in a 5 minute setup. Horrible from close by, but in the distance it's quite ok.
