DOGA
From NSwiki, the NationStates encyclopedia.
DoGA ([do:ga] means 'Animation' or 'moving picture' in Japanese)
DOGA is a popular program among NationStates players for creating 3D artwork. It is akin to virtual LEGO in that you use pre-made 'parts' to build a model. Just as with LEGO you are only limited by your creativity in how you put those parts together. Unlike LEGO you always have enough pieces and they come in whatever color you want.
The simplest version of DOGA (L1) is still free, but you will need to pay for the more advanced versions if you wish to render images.
