My bryce suggestion was just based on the images they showed and their prefrence for using corel 2d program for design:) most of those 3d programs are hard to learn and cost a fortune and not nessasary if one just wants to assemble several fairly flat items. those pieces could be done in bryce in about 10 minutes they'd take a lot longer in many 3d modeling programs. where the 3d modelers realy shine is organic curved shapes. and you can't get much easyer then bryce which was a stipulation of their request. and it's cheeper then the full versions of all the rest, as well as being a great rendering engine for poser images:)
