The only 3D software I've ever used was Sculptris and Blender, briefly. I liked the former a lot since clay has been something I've always had a bit of a knack for, and as for the latter... the interface was just terrible and I couldn't get into it. I'm not even sure the computer I have now is built for modeling. It melts the house playing a youtube video, so I shudder to think what would happen if I tried to do any 3D stuff with it. One reason I like Inkscape so much is that it's like 2D modeling. Almost everything in the above pictures started as a circle or square and I just molded them around a lot until I got a good-looking piece. I'd never seen anything like that before and it felt very natural for me to use. It's rekindled a passion, almost! I fantasized about getting back into painting again last night, but that might still be too much for now.
